Hi - this is my first post, I hope someone can help me!
I had my six month old tom neutered yesterday. It all went very well except that his sister no longer seems to recognise him (she hisses and growls at him).
I appreciate that cats recognise each other by smell. However, my tom is very upset and confused by his sister's behaviour (they were very close and affectionate before). Could his smell have changed that much in 24 hours? Will she get over the change (I think she might be in season at the moment, which might not be helping matters).
Any advice or shared experiences would be very welcome...
