Cool Cats and Cool Pets MILK Tokens: How Holders Earn Them
Cool Cats and Cool Pets were Ethereum NFT collections whose holders were tied to the MILK token, a reward token that was never a simple investment. This guide explains how the rewards were meant to work, what has changed since, and how to check the current status of MILK and your NFTs.
By the DappsAtlas editorial team · Updated

What Cool Cats is and why holders were rewarded
Cool Cats is an NFT collection on Ethereum made up of 9,999 randomly generated and stylistically curated cat images. Each cat is a unique token recorded on the blockchain, which means ownership is proven by the wallet that holds it rather than by a file on a website.
The collection became well known during the 2021 and 2022 NFT boom, when many PFP (profile picture) projects gained followings on social media and in NFT communities. Cool Cats stood out because the project was built around holder benefits. Owning a cat was meant to give access to things beyond the image itself, such as community events, claims and a shared token economy.
The project's own documentation and third-party collection pages describe the cats as randomly generated with curated traits. Public listings usually show the total supply as 9,999, and that figure is the one to use when you compare the collection with others.
If you are new to the topic, think of the NFT as a membership key and a collectible at the same time. Its market value depends on demand, rarity, the community around it and the project's reputation. None of these factors is fixed, so the value of a Cool Cat can move up or down without warning.
Before buying or relying on any collection, check the contract address against the project's official announcements, and make sure the collection page you use lists the same contract. Counterfeit collections copy names and artwork, and a copy has no link to the original project's rewards.
What Cool Pets was and how it relates to Cool Cats
Cool Pets was a second series tied to the Cool Cats ecosystem. Sources reviewed for this guide describe it as a limited series of 19,999 tokens, released in early 2022. The name signals the connection: pets were offered to the community as a companion product to the original cats.
The launch drew attention for a practical reason. Reports at the time described high Ethereum network fees, often called gas, which made minting costly for many buyers. Coverage of the drop noted that holders paid gas fees in exchange for the token, and that a portion of supply was allocated to the team. These are the kinds of details that change how a launch is remembered, so it is worth reading the original mint terms rather than relying on a summary.
For a reader today, the key point is that Cool Pets are separate tokens from Cool Cats, even though they were linked in marketing and community discussion. A pet's status, value and rewards depend on the rules that applied to the pet series, which may differ from the cat rules.
When you look up a Cool Pets item, check its contract address and the series it belongs to. Collection pages often mix up the two series or show old reward notes, so compare what you see with the project's current communication before you act on it.
How MILK rewards worked for Cool Cats and Cool Pets holders
Holders of the Cool Cats and Cool Pets collections were linked to the MILK token. Public descriptions of the arrangement describe MILK as the reward token native to the Cool Cats project, and they say pet holders could receive MILK rewards tied to ownership.
The basic logic of such schemes is simple. A project issues a fungible token and distributes it to wallets that hold qualifying NFTs, either on a schedule or through a claim process. The holder then has a balance of MILK that can be kept, traded or used inside the project's ecosystem, if the project allows that use.
The mechanics can vary widely across projects and over time. Common variables include:
- Which NFTs qualify, such as one series or both
- How often rewards are issued or whether issuance has stopped
- Whether claims happen through a website, a contract or a manual process
- Whether rewards can be traded freely or are restricted
Because these details change, do not assume that a reward described in an older article still applies. Check the project's current terms and any claim page it officially publishes. If you are offered a claim by someone who contacts you directly, treat it as suspicious.
What readers can do now is confirm three things: whether the reward program is still active, whether your wallet qualifies under the current rules, and whether any tokens are visible in the wallet you actually use.
What the MILK token is and why it is not the MLK token
MILK is the token linked to Cool Cats. It is a different asset from MLK, the token of the separate project Mil.k. Mixing up these two names is a common mistake, and it can lead to buying the wrong token or interacting with a fake contract.
Before you research MILK, confirm the exact ticker, the blockchain it lives on and the contract address. Market data pages often list several tokens with similar names. The price shown on one page may refer to a different token, a wrapped version or a bridged copy. Matching the contract address is the most reliable check.
MILK's market profile is also highly volatile. Small or reward-based tokens can trade in thin markets, where a modest trade moves the price a lot. Some tokens in this category have very low unit prices, which can make them look cheap, but the total market value and the number of holders matter far more than the unit price.
If you own MILK, consider these questions:
- Is the token still listed on a market you trust?
- Is the contract the one the project officially names?
- Is there a visible trading history, and how deep is the market?
- Does the project say what the token is for going forward?
None of these questions has a fixed answer that will hold for long. Recheck them whenever you make a decision about the token.
Animoca Brands' 2025 stake and what it may mean for holders
Sources reviewed for this guide report that Animoca Brands took a majority stake in Cool Cats in August 2025. Animoca is a long-established Web3 and gaming company, and coverage of the deal described the collection's large sales history as part of the reason for the investment.
An ownership change like this can affect a collection in several ways. It may change who makes decisions about the brand, the roadmap and the reward schedule. It may also change how holders communicate with the project. Ownership news does not automatically change the rules for MILK or for NFT holders, but it is a reason to recheck the terms you relied on in the past.
For a holder, the practical steps are simple. Look at the official announcements from the project and from the new majority owner, if they publish any. Compare them with older material. If something important is unclear, wait for a clear statement before you move assets.
Also keep in mind that corporate deals, like any business news, can be described differently across outlets. Stick to the primary source where possible, and note the date of any report you read. A clear date helps you tell a current fact from a historical one.
How to check MILK's current status and price safely
Because MILK's price and holder count change often, this guide does not give a current price. Instead, it explains how to check the latest figures yourself, which is more useful than a number that may be stale by the time you read it.
Use at least two independent sources. A market data service can show price history, volume, circulating supply and the list of exchanges. The project's official site or verified social channels should show the contract address and any announcements. If the two disagree, trust the contract address and the official notice over any single price figure.
Check these items on each visit:
- The contract address on the market page matches the one the project publishes
- The trading volume is large enough that a small trade will not move the price sharply
- Any supply changes, burns or new issuance are explained in the project's notices
- The date on the data is recent
If you cannot find an official contract address, do not buy or swap the token. An absence of clear information is itself a warning sign. Many scams work by creating a token with a familiar name and a convincing chart, and then attracting buyers who never check the contract.
Treat any price you read as a snapshot rather than a promise. Past prices, including those from the early reward period, do not show what the token will be worth later.
Holder perks, licenses and events beyond the token
Membership-style NFTs often came with benefits beyond the token itself. Public descriptions of the Cool Cats collection say holders could take part in exclusive events and NFT claims, and that the project's license terms for the artwork were tied to holding a cat. A license of this kind determines what you may do with the image, such as using it for personal display, merchandise or commercial work.
Reading the license matters more than most holders expect. A personal-use license is not the same as a commercial license, and the terms can change or be clarified over time. If you plan to use the artwork in a business, get the current license text directly from the project, and do not rely on a secondary summary.
Events and claims are also time-limited. An event listed in an older post may have ended, and a claim may have closed or moved. Holders should look for the newest notice from the project, not the earliest one they can find.
A useful habit is to keep a short personal record. Note the contract address you hold, the date you checked the terms, the license version you read and any claim you completed. This record helps if the project later changes its rules or if you need to show proof of ownership.
Scams, approvals and wallet safety for NFT holders
Holders of popular NFT projects are frequent targets for fraud. Most attacks do not break the blockchain. They trick people into signing something harmful or giving away access. The following habits protect you whatever the token or collection.
Watch for these warning signs:
- Direct messages offering a claim, airdrop or support for your wallet
- Links to a claim page that you did not reach from the official site
- Requests for your seed phrase or private key, which no legitimate project needs
- Pressure to act in minutes, or a countdown timer on a claim page
- Fake contract addresses copied from a real project's name
Before you sign any transaction, read what it does. A wallet approval can give a contract permission to move your tokens later, and some approvals are open-ended. Revoke approvals you no longer need, using a reputable approval-management tool that you find yourself, not through a link from a message.
Use a separate wallet for NFT activity if you can, and keep only the funds you need in it. Store your seed phrase offline, never in a screenshot or cloud note. If you suspect a compromise, move your remaining assets to a fresh wallet you control and report the incident to the platform you used.
No project will ask for your seed phrase, and no legitimate reward requires you to send tokens first to receive more.
Where to trade or view Cool Cats and Cool Pets items
If you want to trade or view Cool Cats or Cool Pets items, you have several options. The right one depends on what you want to do and how comfortable you are with wallets and fees.
OpenSea is a large general NFT marketplace where many collections are listed for buying, selling and making offers. Element Market is a multi-chain aggregator that gathers listings from several venues, which can help you find a price across markets. Sudoswap is a decentralized automated market maker that trades NFTs against pools, and its versions have different features, so check which one you are using. LooksRare is an Ethereum marketplace with its own reward program, which can change over time.
When you compare venues, look at these points:
- Whether the marketplace lists the correct contract address for the collection
- The fees you pay to list, buy or sell, including Ethereum network fees
- Whether the venue supports the series you hold, since Cool Cats and Cool Pets are separate
- How easy it is to see the item's history and current offers
Always connect your wallet only to the marketplace's official domain, which you should type or bookmark yourself. Compare any listing price with recent sales before you accept it, because a low listing can be a trap or a mistake.
For readers who want to browse rather than trade, a collection page on a reputable marketplace is a good starting point. Use it to check the contract, the supply and the activity, then cross-check with the project's official material.
Frequently asked questions
What is the connection between Cool Cats and MILK?
Cool Cats is an Ethereum NFT collection of 9,999 generated cat images. MILK is the token associated with the Cool Cats project. Owning a Cool Cat was the basis for holder perks, and the Cool Pets drop extended that reward model to a second set of tokens.
Are Cool Pets the same as Cool Cats?
Sources reviewed for this guide describe Cool Pets as a series with a limit of 19,999 tokens, launched in early 2022. Pet holders were described as receiving MILK rewards. Confirm the exact supply and reward terms on the project's own channels, because public summaries can be out of date.
Can I still earn MILK just by holding a Cool Cat or Cool Pet?
Not necessarily. Reward schemes depend on the project's rules at the time, and the rules can change or end. Treat any past reward as a historical event and check the current terms before assuming you can claim anything. A token's market price can also fall to very low levels, so you should not count on rewards as income.
Is MILK the same as the MLK token from Mil.k?
Mil.k is a separate Web3 rewards project with its own MLK token, which its materials describe as moving from one chain to Arbitrum. It is not the same as the MILK token linked to Cool Cats. Always check the ticker, contract address and project name before buying, swapping or claiming anything.
How do I verify the MILK token safely?
Start with the project's official channels and verified contract information, then check the token's listing on a reputable market data service. Compare the contract address with the one the project publishes. Do not connect your wallet to a link you received in a direct message or an unexpected pop-up.
