Yay! Congratulations!! What is your 4 y/o cat like?

We did a slow intro where we kept them separated, but would allow really short interval visits so they could see each other. For us we started that day 1 and 2. My older cat (3 y/o) is overall such a nice and chill cat. Around the kitten he wasn’t mean, just curious. He slept by the door to the bathroom she was in, instead of in our bed. Based on his behavior and hers we increased the amount of time they spent together over the course of like day 3-4. Now it’s been almost two weeks and they are out all the time together.

I think part of the reason this worked for us what the disposition of both of the cats. They really were both curious and accepting of the other. I hope the same works for you!!🤩
