This past weekend my husband and I took our kitten with us to my parents house. They have two adult cats who didn't seem aggressive toward my kitten but were not openly friendly either. They left her alone unless they thought she was invading their space and then would hiss. Other than that we didn't see any open aggression. When we arrived back home, our kitten immediately became distant to both of us. She is normally extremely active and loving and this was not the case. Also, she is limping slightly, sleeping a lot and not eating much? Could she be depressed or do you think their might have been a cat fight that we didn't know about?

It sounds like the kitten might just be spooked from being out it's
Element. Give the little bugger a little space and it'll be back to
norm.

Unless you left the kitten unsupervised with the other cats for some time, it's unlikely you would not have heard a fight.

Your probably just being overly sensitive since you've noticed her behaviour. She is probably freaked out at being put her into that situation, and is still a little unsure about her safety.

As above - Give her a few days, and some extra love, and she should come back to normal.
