Well she has one called Bandit (in the scene where dwight starts a fire she throws it through the roof after oscar, and it crashes back through it :D)the one dwight killed was called Sprinkles (there was claw marks in the inside of the freezer!)
As for jim he said he was helping his parents out by buyin their house off them giving them the money, house was probably too big for them, and he was saving money by skipping the estate agent.

Besides Bandit and Sprinkles, Angela has Nana Mimi, Princess Lady (the $7,000 cat) and Mr. Ash. There are more, I think, but I don't know their names.

The only ones that I know of are Bandit(who she throws up to Oscar in the ceiling) and sprinkles(the sick one who Dwight killed.) and I know nothing about Jim's parents and they sold him the house because i think the were retiring and moving. It's a really creepy house!
