Melchoir and my new living arrangement.

I've had Melchoir for a few months now - he's a very grumpy Hedgie, always balls up when I pick him up, and bites on occasion!

I've started feeding him a Cat food from the suggested list on this site, and it seems like he's gotten more and more grumpy since then! His poops look fine, though, and it's not too unusual and drastic, so I imagine he's just being a grump.

Anyway - I'm posting because my beau and I of nearly two years are moving in together in July. He has a cat that he'll be bringing with him, and I'm trying to figure out the best arrangement here.

I know Hedgies don't get along with other animals, so I'll probably put him in one room and keep the door closed - but is there anything else you guys can suggest to make this transition not so awful?

Is there anything specific about HedgeHogs and Cats living together I should know?

Thanks guys!
