So, I adopted a second kitten almost two weeks ago. Followed all the steps about properly introducing them and they more or less get along great. They roll around and play with each other, chirp all the time, and just are both very friendly. Ares, my first kitten, is 6 months old and wopping 7.6 pounds (the vet is amazed at how big he is - and he's not over weight for his body structure.) Corvo, the new one, is just a little over 5 months and must have been the runt of his litter. He's just a little over 5 pounds and very scrawny. I was expecting Ares to be a little rough with him (not on purpose) so I tend to keep a close eye on them when they're playing. What I noticed, though, was not at all what I expected. The first time I introduced a toy into their play Corvo instantly ran to it, took it in his mouth, and ran away from Ares into a corner. Ares, not understanding why the play stopped, chirped and ran over to him only to get growled at. Ares backed off immediately and sat about a foot away from him. This happens every time I throw a toy down for them to play with. It's gotten to the point that when Ares sees a toy when Corvo is in the room, he'll walk away from it and stay as far from Corvo as possible until the toy is removed - then they go back to playing. Is this normal? How can I go about correcting this behavior? Corvo also tends to growl is Ares comes over to sniff his food - which is something else I'm hoping to work on. Thanks!
