I’m so sorry to hear about the unpleasant complications you’ve run into since December! A standard neuter has a swift recovery, but considering the bladder stitching complication, Rosco’s neuter definitely was more physical strenuous than a typical neuter.
An operation like that can take a lot out of a bun, and recovery may be slow. Eating is really important though, because he needs strength to recover and he needs his gut moving or he’ll get sick in another way. Did the vet recommend force-feeding Critical Care?
If he has not eaten, he really needs to eat, whether you mash up pellets for him in a bit of water, or get Critical Care (recommended for rabbits recovering from surgeries). Force-feeding is important.
Just to double-check, he is separated from the female and the babies now? It’s best to do that so he can recover to himself, in a low-stress environment.
