Why is my rabbit chewing her cage bars even with room access?

If she will allow, check her teeth for overgrowth or malocclusion. You may need to have her examined by your veterinarian or a vet experienced in treating rabbits if she won't let you. The vet can also check the back teeth to see if they need grinding. Sometimes, they can wear unevenly causing uncomfortable points. She may also be bored or stressed. Provide ample playtime outside of the cage and provide a variety of toys to keep her engaged while in the cage.

Chewing is a natural and essential behavior for rabbits to keep their constantly growing teeth worn down. Ensure he has permanent access to good quality fresh hay and also rabbit safe chewing blocks such as timber from apple trees or commercial chew toys etc, a feed ball which drops pellets as he rolls it can be very helpful. Ensure he hs daily exercise for mental and physical stimulation

This is very normal rabbit behavior. I suggest you try to give her plenty of things that she is allowed to chew on like woven hay structures, wood blocks, etc. This website has a lot of options: https://barksandbunnies.co.uk/ As for the places she has already chewed, you can try to spray Bitter Apple on those areas. Sometimes it deters them, sometimes not. Rabbits really are meant to be outdoors. https://www.amazon.co.uk/s?k=c%26g+no+chew&ref=nb_sb_noss_2

Some hamsters may continue to chew on cage bars just out of interest even when the rest of the environment is enriched. It can be problematic if Lulu accidentally chews on something sharp and causes damage to her mouth, or if she gets a paw or even her head stuck between the bars. If you've tried enriching her environment with little success, switching to a different enclosure such as a tank or solid side cage may help eliminate the behavior.

No health reasons typically associated with this behavior. Often times they start chewing things because they figured out they can and because they get bored. You may have to change to a plastic play pen that is stronger and make sure he has toys that you rotate frequently to keep him entertained

He may be bored with the items in his cage. Keep a variety of toys and chew treats for him and rotate their usage to prevent boredom. You can also let him out of his cage for play and exercise each day. Supervision is required so he doesn't chew cords or wires. Rabbits do sleep and it would be good to provide a dark area or turn the lights off at night so he can rest.

It sounds as though Bright is becoming destructive because she is bored. I would recommend penning her into a room where she can be supervised. Cords should be out of reach or protected with plastic piping. I would invest in some rabbit safe toys. Treat balls are fun for them or toys with bells. You can also fill toilet paper tubes with hay to keep Bright preoccupied.
