Hello. I saw a similar recent post on introducing a new sphynx kitten and wanted to get some opinions on my situation. I have a 2 yr old neutered male sphynx and got a 2nd male sphynx 2 weeks ago (he is 15 wks old, neutered). I segregated him in a separate room for the first 9 days and followed recommended steps for introducing - feeding on opposite sides of closed door, swapping rooms etc. There was some initial hissing on the part of my older cat but once this stopped I decided to introduce. Did short introductions giving them both treats. There was no hissing or aggression. Now though the older sphynx is chasing the kitten down and pinning him to the ground and biting and kicking him very roughly. The kitten sometimes squeaks and then runs and hides. Any time he runs (even in play) the older cat chases him and repeats the above. I do notice the older cat’s tail whipping back and forth before he pounces but otherwise he is silent. After the “attack” the older cat is making what sounds like loud sniffing sounds. Does this sound like normal behaviour? Should i continue introducing or keep them separate? I don’t want the behaviour to get worse but I don’t know what it means? Currently the kitten still spends the majority of time separated in his room. Thanks for any advice!!!
