Female rabbits need to be spayed. It’s very probable they’ll die of uterine cancer by the time they reach five years old if not spayed. We spayed Bunny just in time. At five years, her uterus contained tumors. Luckily they had not metastasized so she lived another 6 1/2 years.
Two weeks and there’s still recovery problems? I think something is wrong. My experience, three female rabbits, is that although they weren’t very perky at first, they bounded back to appearing to be fully recovered in about 4 days. Neither of the three had cone collars. Neither chewed at the incision site.
Her skin at the incision site should be completely healed after two weeks. I wonder if she needs the collar on. I wouldn’t think she’d chew her skin if she could reach the incision site. If she has sores, I’d think she should be allowed to lick them, it’s a natural and harmless for an animal. I don’t know about rabbits, but dog saliva is acidic and has natural antibiotic characteristics. My mother grew up on a farm and in the days before anti-biotics, if you had a bad cut, the home remedy was to let the dog lick it!.
One question, not so relevant now. Is the vet you are seeing a vet that specializes in rabbits? The vet, the same one, that did my three girls specializes in rabbits.
