Ditto to everyone else… neuter him. It’s a tad expensive if finances are tight (like mine, lol… we are splitting the procedure 50/50), but it’s definitely worth it in the end. Your bunbun will be so much happier, friendlier, and healthier if his mind isn’t constantly being taken over by hormones.
The spritz bottle doesn’t always work. I tried that with Oliver to deter him from crawling under the sofa (extracting him is such a pain) only to discover that he actually enjoys water. I guess I should have already known this, since he’s been known to play in his water dish.
Anyway. Does your bunny have any toys to chew? Oliver is a huge fan of parsley rolls; Peter’s Rabbit Supply company makes them. They are like rabbit doggie bones and last a couple days at least. There are also a lot of other toys out there, like balls made of hay, wood sticks and flavored wooden blocks, that encourage chewing. Every time Oliver tries to snack on my clothing, I tell him no (which in our house is a loud, sharp “AAH!”) and offer him something more appropriate.
Also, I would love to see pictures of your bunny! I think French Lops are so interesting.
