Is Cat Food...

Harmful to rabbits, whilst having Ryleigh running around I just caught him nibbling the cat biscuits the little monster, they won't poison him will they? I don't know whether to laugh or cry...

It's bad for them but I'm sure they'll be fine if it's just a one time thing.
Kenzo used to do the most silly things to get to the cat food, we had to hide it from him when he was indoors but she still managed to eat some a few times, and he was fine.

As a one off he should be fine, I had a toothless rabbit manage to eat a giant dog biscuit once....never occurred to me he'd be able to get it in his mouth, let alone chew it.

Definately a one time thing, the others don't bother with the cat bisuits but he seems to enjoy the taste
