There is a risk he could get infatuated with the cat. I had an unneutered rabbit who developped a crush on my dog, after they’d been living in the same household for a whole year. It stopped after I had the bun neutered, but it was rather problematic while it was going on. He would pee-and poopmark on the sofa, and he pursued the dog relentlessly. She was a very gentle soul, but she didnt enjoy being circled and peed on and nippped for attention. It was very stressful for the bun too, he barely got any rest.

If your rabbit and cat are living in the same household, they know of each other’s presences. Rabbits and cats have very keen sense of smell.  So I dont think your rabbit will perceive your cat as sth bad even if you wait until after his neuter with introduction.

I have never had a cat (sadly, Im allergic), but we have several members who have a cat and buns, f ex moderator Dana, so Im sure you will get good tips on safe intro from people with hands-on experience 🙂

Never had any real experience with un-neutered buns and cats, but agree with your strategy on just slow introductions and lots of supervision at first. I didn’t really do anything too special with mine, but with new buns I like to let the buns out to explore when the cat is most sleepy. I also make sure to play with my cat when he is getting zoomies or “crazy eyes” as I call them, so he doesn’t decide to chase a bunny instead of a toy.
