New bunny jumping out of cage: Is it lonely or a behavior issue?

Max sounds like he is trying to get your attention :) Rabbits are highly social creatures and when kept in small cages with little stimulation often get very bored and destructive. Is it possible for you to have "play time" with Max where he is allowed to run around loose in a playpen area inside the house, or in a fenced, safe backyard? Also, consider rabbit-safe toys like cardboard boxes and plenty of sticks and hay to chew on, for all your rabbits. Hope that helps!

This sounds potentially quite dangerous as Bun Bun could suffer trauma or predation while out on her adventures. I would recommend keeping her in a rabbit enclosure or a closed room inside your house, especially when you’re leaving the house and not supervising her. She can free roam when you’re there to keep an eye on her, but if you’re opening the door to leave or having people over, she should be confined. This will prevent her running out the door again. As for not remembering your sister, she probably does but may still be on high alert from her outside events and may need some time to calm down and respond more normally to people. As a prey species, rabbits are always on high alert for dangers, and the chemicals in her body need some time to adjust to the change in scenario.

Thank you for using Petco Pet Education Center, formerly Petcoach! Rabbits can do well on their own if bonded to a person and with plenty of enrichment in their enclosure. As an unneutered male, Blackberry may be aggressive towards another rabbit, and they may fight. I hope this helps!

It will take time for Julius to acclimate to his new cage. Provide plenty or toys and places for him to lay. Always have timothy hay or similar grasses available for him to eat. This should be what he eats most of the time. Rabbits will readily use a box if provided. Place a litterbox in the cage for him. Pick up droppings and place them in the box. For urine, use a tissue to soak it up then bury it in the litterbox. Be patient and be consistent.

Thank you for using Petco Pet Education Center, formerly Petcoach! Rabbits sometimes do this behavior when they are scared or as a form of play. If Louie is not acting like himself, I recommend having him seen by a vet as soon as possible. If he has resumed normal behavior, you can monitor him at home to make sure he continues eating, drinking, and having normal bowel movements. I recommend filming the behavior of you are able to in case Louie continues doing it and I would be happy to take a look.

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.

Hi there and thanks for using Petco Pet Education Center, formerly Petcoach! Usually aggression in our pets can be altered a bit by removing excess testosterone with neutering. While it is not impossible he is lonely-likely he is frustrated with the removal of his mates each time. Neutering may help with his need for female attention as well as curbing unwanted aggression due to excess testosterone. I hope this helps!
