Finn has been through far to much himself, with several operations his had. He needs special care and i don't think i could trust anyone enough to do this. Plus his helped me deal with the breakup of a long term relationship. Rehoming him would probably cause me a fair bit of harm. I am not sure i could let him go. Id feel as if i was being punished for doing good by bonding him. But I am hoping it wont come to that.
Bunnies are destructive by nature yes...but not all rabbits are big chewers like she is. Some are better indoors then others. Finn was never a big chewer before he lost his teeth, neither was his sister before she passed away. My lion head before wasn't a big chewer either, or the rabbit before that. But I know some do express more "wild" like behaviour.
I am aware of the catch 22 situation which is why i have been letting her out but on shorter time intervals and build the time up. I just don't trust her at the moment because of her behaviour, so i need to build up that trust.
She was only spayed 4 months ago, and with the time of year. I just hope she calms down.
I can understand, I went through hell with my boy Snoopy and wouldn't have given him up under any circumstances. but, if it came to it and I couldn't deal with him and his partner, I'd either have to deal with the damage or do what is best. the thing is, you're not being punished by doing something good. bunnies do need companions but sometimes you need to adapt to said bunny.. if one is a chewer you need to root the issue out. I believe its boredom and space.
imho, I always believe there is a reason for bad behaviour. it may not be obvious, but I believe there is always a root cause.
make a forage box, or hide their pellet around the pen. its all well and good having toys but, those can be boring too. you'll need a bit more than that. toys by themselves are boring and without new ones coming in, they don't care for them.
a digging box with soil or sand may be a good idea too. apple sticks or pear sticks make good for them too, they're tasty.
perhaps some mental simulation, such as treat balls or puzzles would be helpful.
there is always something new to try..to entertain them.
I don't believe this is hormones anymore after her spay, 4 months is ample enough time.
re adding more levels, this will not meet said requirements either. they need x amount of space continuously, not x amount of space from combined levels. so I'm not sure it would be any help.
as I said.. if she has shown minimal destructive behaviour outside of the pen, then I think you're perhaps being a bit over cautious at that point. but the problem is, they will always destroy something. Luna wasn't a destroyer, but she's chewed a few holes in blankets and a few wires..
the destruction is probably from boredom and not enough space to move about in. along with that, rabbits get very frustrated about being put back in. they want x amount of space all the time, not for a few minutes. I know mine throw a fit at bed time from being placed back in their pen. so that will also add to the frustration, unfortunately mine live in my bedroom, and I have to sleep myself.
pet remedy is wonderful, it helps calm them down and any anxiety. perhaps she is even feeling some anxiety and stress hence her destructive behaviour. I can say, it really made a difference for mine. the 60 day diffuser is the best, and spraying it around their pen helps wonders too.
the unfortunate thing is....if you really can not allow more space, have them free roam, or allow a decent amount of time out per day (8-12 hours) then rehoming both may be your only option. they will need to stick together now, or it will cause ill-health to both of them being separated. however, there are plenty of other options for your to try for the moment.
