Hey there
Is she showing signs of boredom/loneliness? There are lots of things you can give her to prevent boredom. Foraging toys, various hidey boxes etc. Rearranging tunnels, boxes and toys in her environment can keep her busy exploring. If you think she may be lonely, some owners have had success giving their bunnies a stuffed toy to keep them company, and their bunny with cuddle with it and groom it. Some bunnies however will chew and destroy so you will have to keep watch if you decide to do that. Paper bags stuffed with hay and a few pellets or treats, a cardboard box with the same. Any time you can spend with her is obviously a good thing, but it doesn’t have to be a long time to be quality time. How do you go with giving her time out of her cage? If you are home but aren’t able to spend one on one time with her, you could still let her out into a playpen to run around which could give her more time to stretch her legs and play. It depends what your cage setup is for her.
