I have two Holland lop eared rabbits that are brother and sister from the same litter. They just turned 11 months old the other day. I had them living in two separate hutches in my home where they could interact safely (without any accidental kits). I had them spayed and neutered at a veterinarian near me two weeks ago. They both were doing perfectly fine until today I came home to find the male bunny lying dead in his hutch. He had plenty of pellets, hay, and water, toys, space to stretch out, a clean litter box. He was so young and the vet told me he was healthy when he went in for surgery. I am absolutely beside myself right now. I’m going to be calling the vet tomorrow of course being that they’re not open at this hour. I’m very confused what could have happened and sad and worried for my other bun (the female). Any advice, thoughts, or help with this issue would be much appreciated. Has anyone else gone through this? Does anyone know any possible causes? What extra precautions should I take with my female now?
