I decided to revisit the Talking Kitty Cat fandom page and I remembered there were three or four cats that don't have a name. Several of them were featured in Sylvester Goes to Jail and one cat in Save Gibson. 

1. A fluffy cat who has a southern meow at Steve while looking for Sylvester in the pound. (Presumably a lynx ragdoll mix) 

2. Another cat who was begging to be let out. (Lightish beige cat)

3. A female cat that's orange and white (name is Marie) that comes up to Steve while he was talking to her.

4. One cat who was asking Steve to pick him and has a southern accent but the cat died in 2013.

5. A gray and white cat that's next to the cat with the southern accent and just stared at Steve and is above Sylvester's cage but later reappears in Todd's trailer in a scrapyard hiding in one of the shelves that has a can of beans.

6. A gray female cat who lives in Todd's trailer in the scrapyard and was eerily singing before Steve tells her to be quiet while he was looking for Gibson.

Apart from the one cat that's named Marie, what kind of names would you give these cats? 

Here's the videos on where these cats appear
