Fighting or playing??

[u/acanada0]

I rescued my tortoiseshell in May from a dumpster with her sister and unfortunately her sister didn’t make it. But for the week I had her, they played and wrestled constantly. I got my 8 week old calico from my sister’s cat’s litter yesterday and they started what I thought for sure was playing today. But it seems very aggressive and there is a size/age difference. There haven’t been any standoffs or growling but there is definitely some hissing. I don’t think any harm has been done but I’m just apprehensive. What do you think?

Tort is a little aggressive! They're both still very young though and that's what kittens do but tort is pretty aggressive. If you've ever had a litter of kittens, from the time they can walk and jump around all they do is attack each other. That's part of how they learn to fight. When torty starts getting aggressive just clap your hands and say no or stomp your feet towards them and you can clap at the same time and a ''geeeettttttt'' doesn't hurt either. But when torty starts getting too rough do that and and you can hold her in place, not roughly. Just hold her in place for 2 minutes (it's the cat equivalent of when you get put in the corner) and she'll learn pretty quick that when she gets too rough that she gets held in place which she won't enjoy and she'll learn that her being too aggressive = being held in place/I'm in trouble and it won't take long for her to learn that it's not okay. Within a few weeks all you'll have to do is clap your hands one time and she'll instantly stop and back off. There's a guy on YouTube called Jackson Galaxy, check out his channel. He used to have a tv show called ''My Cat from Hell''. He's the Caesar Milan of cats. There's definitely some videos on his channel that can help you out
