The family I am currently living with got a cat about 6 months ago (she is also 6 months old).
Had zero problems with her until ~2 months ago. She started being extremely rude and annoying.
I can best describe it with some examples:
1) We all eat, she goes under the table and jumps on somebody from below. Claws right into our legs or hands if we had them under the table for some reason. I have some serious injuries already. My arm looks like I was in war.
2) Something she only does with me. If I walk without shoes on she always jumps my feet and trys to bite me and scratches me. Putting her away only makes her attack again. Only way to stop her is to put some shoes on or to carry her into another room.
3) She fights my dog for the dogs food. I always have to seperate the cat when feeding my dog, or she would simply eat everything away. This cat eats fucking dogfood
4) We build a scratch tree for her, but she just doesnt want to fucking use it. Instead she scratches all the old and valuable furniture. The old man in the house is getting extremely pissed by her and starts being aggressive. I try to calm him down and not to attack the cat but I think he is reaching his limit; and I can understand him. The furniture is really expensive and it would be a shame if a cat damages it.
She was a wonderfull cat until two months ago... calm, yet playfull. She has a huge garden to play in, but now she refuses to go outside because it's getting colder.
My dog isnt a problem. She's leaving the cat completely alone. She's ignoring the cat 100%, and for the most time the cat doesnt give a f about my dog, too.
We thought it might be because of her hormones... she's just about that age where she could start breeding, so we took her to the vet and got her sterilized. After ~4 days of being silent and groggy from the operation, she is just back to being a huge cunt. Old behavior, no changes.
My friend had a cat once, and it didnt show any of this antisocial behavior.
What did we do wrong, and what can we do to fix her?
ps.: She is also hungry all the time. All. the. time. If I want to eat a banana in the kitchen she trys to steal it from me....
Yet the vet says that she is actually too fat and eats too much. How does this work, since we are not overfeeding her in any way?!
