My family's cats are named Jack and Lola, named by my eldest sister who was their original owner. (She got them as kittens, but wasn't able to care for them due to med school).

They're both healthy adults, and doing great! Although Jack is a chubby, bitey bastard at times. Lola is a sweetheart, though, if a tad fussy about what she eats at times. Historically, anyway.
