Im getting a bunny can i put him together with my tortoise

Hi
I have just got 2 bunnies myself, Poppy & Daisy. I have not put them with the baby tort as she is in her own separate pen anyway, but they have been out with Molly and apart from giving each other a smell they were OK. I took them to the vet tonight to get their vaccinations and spoke to the vet about it, she said torts & rabbits get on OK, the only thing you have to careful of, is if the buns flip the torts over, but as long as you keep an eye on them they should be Ok
