I know this is a little off subject, but I have an outside cat that consumes some of my time when I'm not on my computer. The cat won't come in the house, so I fixed him a bed in my garage for the cold nights.....I then leave the garage door up about 10" so he can come and go. Plus he has a couple of raccoon friends that stop by during the night to visit.
On these really cold nights (19 deg last night) I would like to use some type of heater under his bed blanket.....preferably the type that plugs into 110v but draws low amperage. They sell many different makes/models at the pet stores, and I'm not sure which is the best to purchase/use.
Any recommendations would be appreciated.
