Reply #17: I second this but don't ask for hay, use straw. It's cheaper

I'd recommend going to any horse barn in NC and asking if they have any old bales that you can have for a feral cat. Most barn owners are animal lovers and we ALL have old bales that we can't feed or use that they'd be happy to let you take.

I also use the insulated dog beds that are self-warming as a cushion with some old towels. You can buy them at any pet shop - they have an insulated barrier that reflects/amplifies the heat of the animal that's lying on it.
