I always thought puppies - but was given a kitten two months ago so have changed my mind! and (apart from the multiple claw lacerations and pin prick teeth marks I have all over my arms and legs at the moment ) she is still cute at 4 months old!!!
The trouble with puppies & kittens is that they soon grow into adults. Max turned into a great, handsome dog but he's a bit to big to be called cute (even tho he still thinks he should be allowed to sit on my knee)
