We have two RSPCA cats that have been with us for 3 weeks now, Paris, DSH female and Socks, DSH male. They came to the RSPCA together but their background is unknown.
The RSPCA told me that Socks had definitely been neutered but they weren't sure about whether Socks had been spayed or not and to look out for it. Tonight, Socks has just jumped on to her back as if he was trying to have his wicked way with her, there was some screaming and Paris jumped up as high as possible onto the back of the sofa.
Should I be worried by this behaviour?
TIA
