– This usually happens with shedding during their molt. You have no reason to trim them, unless they start splitting until the base of the whisker.
– X-PEN! I love x- pens and so do my bunnies. They are cheaper than most cages (though you can make your own with NIC grids, and my bunnies love them, they have lots of room to run around are always happy.
-What do you mean you see stains? Is he peeing on the floor? What bedding do you use? I would clean his litterbox more (every other day). He might want you to put his litterbox where he is peeing. Use white vinegar/ water mixture to help remove the odor and break down the harded feces and urine. I don’t buy the petstore sprays. I try to stay as natural as possible. Is he neutered?
– How old is he? If he has a good healthy diet of hay, vegetables, and fresh water, you don’t need to be feeding pellets.
-Don’t use wood cleaner! Just use some water and sun dry it. My bunnies honestly don’t care whether there toys have their poop and pee on it.
Hope I helped!
