I have two cats. One is my baby, Elly, a rescued feral kitten from the first apartment I ever lived in. She is a big fat sassy kitty now.

She's seen me through a lot - when I'm not feeling well, physically or otherwise, she always comes and curls up with me. She knows how to open doors and her favorite snack food is olives.
The other is my boyfriend's cat, Toku, a Japanese bobtail. He's a complete sweetheart, and very smart (even if we do fight over my pillow at night). We used to have three cats - the third was Toyo. He came from the same litter as Toku, but he passed about this time two years ago from renal failure.
We've thought about getting a dog, but Elly is very territorial so that may have to wait a few years until she's too old to care...
