Ok, my boy Lizzard has been with me for 5 months now. He's my little man. Although he is no longer little anymore. I decided to introduce another male kitten (same father, different mother) and we brought Clark home last night. I did scent swapping and Lizzard knew something was up. Clark's safe place is my spare bedroom. While in there Lizzard on the opposite side of the door was meowing and cooing. So we decided to try a stab at introductions. There was a lot of sniffing followed by Lizzard pinning him and Clark let out a little Yelp. My heart sank. I separated them. I'm trying to pay more attention to Lizz (he's cuddling with me as we speak) but I'm just nervous about this process. Any tips?
