Animals in the Purrfect Apawcalypse universe mostly comprise of cats and dogs, but are known to include other animals, both anthropomorphic and non-anthropomorphic.
The types of animals found depend largely on the location. Kemono Woods and Kemonotown are populated by cats (who stay mostly in the woods) and dogs (who stay mostly in the town). There are few non-canine and non-feline animals living in these areas, with most sticking to their own towns in appropriate biomes (for example, zebras tend not to be found in tundras, but do live commonly in savannas).
As for non-anthropomorphic animals, they exist as they would in the real world, and are indeed eaten. Their coexistence with their more sentient and intelligent counterparts are similar to the real world's example of monkeys and humans. There are evolutionary ties between the two, but they are very different beings.
Lunchlady Piggy[]
Lunchlady Piggy is the only anthropomorphic non-cat, non-dog animal to be spoken of in the games. Her dead body can be found in the background of the cafeteria in Love at Furst Bite, and she is also briefly mentioned in the cafeteria in Patches' Infurno. She was known to hoard chocolate, a food item digestible to pigs, yet a dangerous item for dogs.
Snake and Hamster[]
In Patches' Infurno a snake and hamster can be found in the gym level of the game. The snake can be found by poking a pile of leaves while the hamster (Pancake the hamster to be exact, based off Denny's real life hamster of the same name) by interacting with Tigger's lunch bag. Both animals can be gifted to Rover.
Duckdee[]
One of the more contentious instances of another species occurring within the PA universe is a noticeable cameo of artist and fellow Jaiden Animations employee Duckdee added to the background of the library in Love at Furst Bite. More info can be found here.
Scooby Don't[]
A monkey is implied to have been kept as a pet by a group of four teen dogs in Scooby Don't, a fictional show mentioned in Patches' Infurno.
