i have a rabbit a gpig living together, they've been together for most of the pigs life (they were together in the shop, which is why i bought them both as i didnt want to split them up). after i got them i became aware of the problems of having them together and have watched them closely but they're fine. in fact they're more than fine, they're great together. i've had them over a year now and the one thing i have noticed is that they cant stand being apart. the bunny has free reign of the house (i leave the hatch open - the massive cage is in the lounge) she doesnt stay out long and if i'm giving the pig a cuddle she looks for him. he has really long fur (which i of course brush reg) and she cleans it for him (and he sings, its so cute). i'm not completely niave, but with these two, it really did work and i could never split them up.
