I lost my wonderful blue tortie Burmese Lucy to the effects of a stroke last November. The senior cat in the house is a tortie with white named Penny (age 13) who is generally a cranky and complaining cat even without competition. We got a blue Burmese kitten in December (my husband didn't want to wait) and Chianna entered our home and is now running amuck. She picks on Penny (who outweighs her about 4 to 1 but has poor self esteem), gets into all sorts of mischief (worst of any of the 7 cats I've had) and has started biting unprovoked (as far as I'm concerned). I read that she needs a lot of mental stimulation and we've looted pet stores everywhere for toys. She likes soft plush small toys that she can carry around and bite. Is this just a personality issue and I shouldn't try and expect her to be like Lucy? She does like sleeping in laps and being petted (on her terms) but won't be cuddled and is just as like to bite you if you try and pet her if she's not in the mood. We know about Burmese; we had one and my husband had 2 earlier in his life.
