Cats Against the World is a 36-card, cat-themed fan expansion for Cards Against Humanity. It is not a standalone game. You need a copy of the Cards Against Humanity base game to play it, and the expansion’s cards are shuffled into the base decks. It was launched in 2016 as a fundraiser for SOXRescue, a California cat-rescue nonprofit. Whether you can still buy it today is unclear, so check the seller and shipping status before you commit any money.
What the expansion contains
The expansion adds 36 cards in two types. White cards are answers, and black cards are the prompts that players fill in. The card counts below come from the BoardGameGeek listing, which dates to 2016.
| Card type | Number of cards | Role in play |
|---|---|---|
| White answer cards | 27 | Players submit these to complete a black card |
| Black question cards | 9 | Prompts read aloud each round |
| Total | 36 | Shuffled into the matching base-game decks |
Because the cards slot into the base decks, the expansion adds no new rules. A group that already knows Cards Against Humanity can start using the cat cards in the next round.
What kind of product it is
Cats Against the World is fan-made. Catster describes it as an unofficial expansion, and BoardGameGeek files it under fan expansions for Cards Against Humanity. It is not an official Cards Against Humanity release.

Its simplicity and speed ensure everyone stays engaged and laughing.

The humor is adult. Catster describes the content as adult-themed, and the BoardGameGeek listing sets a suggested age of 17+. The listing’s own product description reads: “Cats Against the World is a parody game for horrible people… who LOVE CATS.” That wording comes from the listing itself, not from a named individual.

The charity behind the launch
The expansion was tied to SOXRescue, which Fast Company described in an August 25, 2016 article by Ben Paynter as a nonprofit supporting homeless and sick cats in California. According to that article, the pack debuted in May 2016, carried a $15.99 retail price, sold 8,000 packs (most of them in the two months before the article), and sent all profits to the charity.
The article also said one purchase could provide food, shelter, and medical treatment for one homeless cat for one week. That was a claim made at launch. It is not a verified measure of impact, and it does not show how the charity’s work looks today. The $15.99 price and the sales figures belong to 2016 and do not describe current pricing or sales. Available sources do not establish whether any donation arrangement is still in place, so do not present the purchase as a current donation.

Is it still available?
The sources disagree, and neither establishes a reliable sales channel.
- Catster (updated August 17, 2026): says the game seems to be no longer available and suggests secondhand marketplaces as a possibility.
- BoardGameGeek listing: says the product is still advertised and orders can be placed, but a user comment on the listing reports that the seller did not respond to purchasers.
No official listing and no verified Amazon product page for the expansion were identified. The Cards Against Humanity base game is a separate product, and it is the item readers will need in any case.

Before you buy
If you find a seller, work through these checks before paying:
- Confirm the seller has a verifiable identity, a returns policy, and a way to contact them.
- Ask for a current stock confirmation in writing before you pay.
- Check the shipping estimate and cost, and confirm the seller ships to your country.
- Pay through a method that offers buyer protection where possible.
- If you receive no order confirmation or reply within a few days, treat the listing as unreliable and do not send further payment.
Deciding whether it is worth pursuing
No alternative edition of the expansion was identified, so the decision comes down to four questions:

Best Value
- In this family card game, draw cards and try to avoid the dreaded Exploding Kitten! Use strategic action cards to skip your turn, shuffle the deck, or defuse the Kitten with laser pointers or catnip sandwiches. The last player standing wins!
- Designed for 2-5 players, ages 7 and up, Exploding Kittens is great for kids, teens, and adults alike. Whether you’re a seasoned gamer or want a casual game to break the ice, this easy-to-learn game is perfect for bringing everyone together.
- Compact for travel, portable for on-the-go, camping, game nights, road trips or a family home evening.
- Includes 56 cards illustrated by The Oatmeal (each featuring a hilarious cartoon with characters such as Tacocat, Rainbow-Ralphing Cat and All-Seeing Goat Wizard) and an instruction manual (that you’ll probably skim).
- Our Story: One of the most successful Kickstarter campaigns ever, the hilarious characters, thoughtful design and gameplay simple enough for a good time but complex enough for ultimate replayability, Exploding Kittens has taken the world by storm, with millions of copies sold and a global fanbase.
- Do you already own the base game? If not, the expansion cannot be used until you get it.
- Can the seller show current stock and reliable shipping? If not, the purchase carries real risk.
- Does the cat-rescue connection matter to you? The fundraising link is historical, so buy for the game, not as a current donation.
- Will the adult humor suit your group? The 17+ listing and the adult-themed content make it a poor fit for mixed-age tables.
If the answers point toward a sure yes, the expansion is a playful add-on for a group that already plays Cards Against Humanity and enjoys cat jokes. If the seller cannot demonstrate stock, the sensible choice is to skip it.
