I’m so very sorry to hear this. You are NOT a bad bunny owner. You called your vet for advice, that’s what a good bunny owner does. Many bunnies get into stuff they shouldn’t, most come out fine. There might well have been sth else underneath, sth you couldn’t have known about. My Yohio stole a bag of jellybeans once. We had another bunny here recently who got into a bag of chewing gum and developped a blockage, that’s really bad, but the bunny pulled through.
Don’t blame yourself. Your intentions wer all good. You opened your heart and home to her, put her on a better diet and you loved her. Rabbits can be very delicate. You said in your first post that you got her from someone who wasn’t treating her right. She could have had an underlying condition from long term bad diet/treatment.
I think you really are cut out to be a bunny owner. Because you care, you have a loving heart and good sense. You did call a vet and you followed the vets advice. That’s why there are vets, because pet-owners can’t know everything. If we did, there wouldn’t be vets. We have to consult with experts. And we are supposed to be able to trust them. I’m not sure your vet gave you bad advice, even if the outcome of course was terrible. Fruit dots are not toxic or anything, they don’t even have gelatine.
Please be kind to yourself now.
