I think this goes beyond play fighting and I really need some help as I may have to give a on of these cats away. 7 days ago I purchased a new kitten, he is roughly 8 weeks old. Around Christmas time I purchased my first kitten who is now 6 months old. After a by the book introduction procedure for the new cat both seem to get along ok. They play rough but no puffy tails or hissing so I think it is just cats being cats. Just now things got weird though. My older kitten keeps walking up behind the 8 week old baby and trying to wrap his entire mouth around the kittens neck (from the back of the neck). It looks like a lion trying to kill a gazelle with a choke hold. He never quite goes through with it as the young one turns on his back and flails his claws which causes the old kitten to move away. Neither hiss or growl when this happens Is this normal and safe cat behavior or is the old cat planning on murder? It looks very, very worrying but with no hissing I cannot be sure. I really need some advice, I cannot leave the house right now out of fear that I will come back to a dead kitten. Is it playful/normal for a big cat to try and wrap his jaws around a smaller cats neck?
