people keep telling me that they arent going to stay bonded bc they are the same sex
Not true!! Many members here have bonded males. One member thought she has a female who turned out to be a male. They bonded before one was fixed but they remained bonded. There was a little moment when the young ones hormones started to effect the bond but he was fixed and the bond was mended promptly.
You may find issues arise between Charlie and Jack just after the neuter as their bodies are going thru a change. I have also heard that sometimes there is a testosterone surge because of the testes being manipulated during the procedure. Either way, they will have hormones still in their systems for roughly 4 weeks. So do observe them closely.
If you see any deterioration in their bond, separate them. After they’ve settled from the surgery you can rebond them. I would not think this would take long at all. But for you to have them bonded pre-neuter and that you are seeing no issues at the moment – I’m guessing you’re going to have no trouble with these too. Lucky you! All bonded bunnies, regardless of sex, can have a falling out for various reasons, but it can be mended.
