if they occasionally eat toilet rolls it's not too much harm but not advisable on a regular basis : paper, cardboard, or material they like to chew or eat can accumulate in the stomach if swallowed in large quantitites, as i don't believe the cellulose is free from additives.. rabbits really love tossing things that are light and I must say sometimes heavy : I recall Chloé pushing a dictionnary which I used to block a door !:lol: she also thieved a watch I had until she destroyed the leather completely but she was so funny going away and jumping all over the place with the watch in her mouth !!! when she was a baby I also gave her a small hard plastic ball with a bell inside that we give to cats to play with and used to go crazy pushing the ball as she could not grap it with her teeth, that occupied her and distracted her attention to attack something else
