Just posting to recommend Warrior Cats RPG, a lovely, well-designed roleplay website that I use for most of my leisure time. There's almost always somebody online, the staff are incredibly efficient and helpful and there are opportunities to get badges and other virtual rewards.
It's based on a series of popular children's books, as its name suggests, but it doesn't require more than a couple of sentences of (provided) research to roleplay a cat in the main roleplay area. Alternatively, there's an extremely popular Other area where you can roleplay dogs, horses, tasmanian devils, even humans... Give it a go. Believe me, it's worth your time.
Thanks for reading!
