I got Jack last year, towards the end of September, and INSTANTLY fell in love… Hard. You couldn’t (and still can’t) tell me he isn’t the CUTEST bunny that ever lived! He quickly picked up the whole idea of using a litter box, and I was eager to give him full run of the apartment. Luckily for me, he isn’t at all interested in chewing on wires, baseboard, fabric, chairs, table legs, etc, so it wasn’t a problem to leave his cage door open 24/7. UNTIL he started PEEING ON EVERYTHING! At first I thought he was forgetting about his litter box training, but he wasn’t peeing outside of the box in his cage. He WAS peeing on books, files, inside of boxes… it was terrible. He also started getting very aggressive… like tossing his litter box around in his cage, bumping my hand, kicking and stomping whenever I tried to clean out his cage… he was acting like a moody teenager! I talked to my mom about his behavior (she’s a veterinarian), and she said that basically, his hormones were kicking in and causing him to act territorially. That’s why he was peeing all over everything… he was marking it as HIS. I couldn’t have that… I AM the top bunny in this household! And so, it was time to get Jack neutered. My mom performed the procedure, but I was still SO SO SO nervous! My little (badly behaved) baby was having SURGERY! In the end, I shouldn’t have worried… it was a relatively simple procedure, and didn’t take very long. When it was over, he was fitted with an e-collar to keep him from bothering the surgery site while it healed, antibiotics to prevent infection, and pain medication. He really was a model patient… I ended up leaving the e-collar off the whole time, and he never once bothered his stitches. *DO NOT DO THIS IF YOURS BOTHERS THE INCISION!* Almost immediately, I noticed a marked change in him… He hasn’t peed on anything since, and even though he gets mad if I clean his cage while he’s inside, he doesn’t if I wait until he leaves. Another bonus? In April of this year, I adopted a second bunny for Jack to play with, a girl this time. Since Jack is neutered, I won’t ever have to worry about little baby bunnies overrunning my house =).
