I have two Kittys (Both female)one is 2 years old and spayed, the other is 10 months old and has not been fixed yet. Yesterday one of my cats ( the 2 year old) got outside and spent the afternoon on the roof. She seems to have burned the bottem of her paws and is having some discomfort walking. Otherwise fine. however, since she came back inside the younger cat has been attacking her non stop rather violently. they have never had a problem before. I'm not sure what to do about it as the older cat is in pain and can't fight back I have seperated them but the younger cats behavior is bizzare. Could the aggression towards the other cat mean the younger cat is in heat?SHe has also been uncharacteristically loving towards me. Could the older cat have come back smelling like something that triggered the younger one to "go into heat?" HELP! I have to drop them off at pet sitters next week while I move anI have no clue what do!they have always been such good buddies before!
It does not sound like she is in heat, but she is becoming an adolescent cat so her hormones are changing and she will probably begin estrus cycles soon. It could be she is trying to "challenge" the alpha cat to gain terretory and rank. Maybe the other kitty picked up a new smell outside that the other does not like.
Question: is there any possible way that the younger cat could be pregnant? That would explain her aggression toward the other cat and her affection toward you. You definately need to get her spayed ASAP.
By the way, welcome to the forum!!
I like most cats better than I like most people. I'll try to be nicer if you try to be smarter.
