A friend of mine had Degu’s… an unusual alternative?

I used to have a pet budgie and he was adorable, I'd quite like a cockatoo as well, although I don't know how well my cat would take it. I feel a little different about having caged birds these days, too, so I'd probably have to let him run free around the flat which might be a bit chaotic!

I’ve got two indoor rabbits and they are slowly destroying my house. Would not recommend.
