Hello, so I have a russian tortoise- lilly. I have her enclosure on the ground. I have 2 cats. one is afraid of the tort and its enclosure but the other seems to think that the dirt is something to play in... woke up this morning and there was dirt everywhere!!!! Needless to say I was pissed!! I am not going to get rid of the cat or lilly. So what can i do to keep the cat out? Are moth balls bad for tortoises? I thought of puting them in there at night and taking them out in the morning. At night when no one is looking is the only time the cat gets in there.. any sugguestions?
