Introducing old cats to kittens can be tricky. The truth is, they usually don't make the best roommates! Kitten energy pairs best with kitten energy. This doesn't mean you can't teach a kitten and an elderly cat to coexist peacefully in a household, it might just be a longer process of getting them acclimated.
This is usually because the older cat isn't as playful, and is more defensive of their personal bubble. Young male cats tend to have a wrestlemania style play, and aren't very socially savvy. They might not respond to subtle cues that the older cat is giving off that they would like some space, and instead will relentlessly pursue and attempt to play. Older cats, especially female cats tend to do things like birdwatch out windows, meticulously groom their paws, and crochet tiny hats.
Eliza and Edgar's owner has been diligently working on a behavior plan that includes a few different categories, but here is a snippet of their actual exposure sessions to each other on either side of the baby gate.
- Reward marker sounds to capture behavior. Each cat was conditioned to their reward marker beforehand. (Eliza = "good!" Edgar = "cluck" sound).
- High value food reward
- wearing Edgar out with toys in his room before sessions with Eliza
- Physical objects on Eliza's side since she is the defensive and insecure one, to allow her to have a home base and not feel like a sitting duck.
- A "shield" (peice of foamboard) nearby in case Eliza becomes stressed and charges at the gate, to interrupt that interaction quickly.
- Eliza's main trigger is direct eye contact from Edgar. Here we are really focusing on capturing and rewarding moments of direct eye contact before she gets too stressed to still be interested in the rewards. Whenever Eliza wants to take a break and go inside of her cardboard box, she can. We try to end each session before that happens and leave things on a good note.
