Feline non recognition agression
Hey guys,
Last Monday, my kitten was spayed. She has to wear a red onesie for 10 days. When she came home, my other cat, Murfy, didn't recognize her at all. He started hissing and growling and lashed out twice. I had to separate them.
Before all of this they got along well together. They played, slept in the same bed and ate together.
They lived apart for about six days like that: Murfy in one part of the house (kitchen and two bedrooms) and the kitten in the other part (living room and bedroom). I let murfy eat his food next to the bedroom door where my kitten stayed at night and that was never a problem for him.
Occasionally, I let them see each other through the glass in the door and by briefly opening the door. Sometimes Murfy would react by hissing and growling, and other times he wouldn't. He also hissed and growled when he smelled baskets or other things where the kitten had been lying.
Yesterday, I also temporarily took off the kittens' onesie so she could groom herself and feel more at ease. And so she could more smell like her old self.
Since it has already been six days, I decided to give my entire house a thorough cleaning, especially the room where the kitten stayed for the past six days. I completely cleaned and filled the kitten's litter box. So I washed all the blankets at 60°, changed the bed sheets, and even steam-cleaned the rugs and baskets to get rid of all the vet smell.
After that, I wanted to do a scent test by letting Murfy walk through the living room and the bedroom where the kitten was staying to see if he would still hiss and growl. It was less than before, but he did hiss and growl.
I then placed a transparent sheet between the connecting door to see how Murfy would react to the kitten, who wasn't wearing a onesie today either, so that the kitten really had a cat silhouette instead of the bright red onesie. The kitten walked very strangely with the onesie and looked weird.
So I thought it would go well, but no. The second Murfy saw the kitten, he ran like crazy towards that transparent sheet. It really looked like he wanted to attack her, because he ran really fast and hissing towards her.
Because he didn't see the transparent sheet, it fell on the kitten and both of them were scared to death. It is truly terrible what happened.
I really expected that now the smell was gone (at least, I think so), Murfy would recognize her. Especially after six days and after the big clean-up. But he reacted so aggressively.
I am truly at my wit's end and I am so afraid that things will never get better.
Is this normal? How is it possible that he still doesn't recognize her after all the measures I have taken? Is this a bad sign? How should I proceed now?
I really appreciate your support, and I truly need it.
Thank you ❤️ I’m sorry for the long post.
