My current city gets pretty cold sometimes and was wondering how other cat owners keep their cats warm during cold seasons. I asked for advice from a co-worker who is also a cat owner and recommended heated cat beds, i am pretty new to this but just wanted to know if anyone else here uses these heated beds. Here is how they look like http://www.petstreetmall.com/Heated-Cat-Beds/373.html just in case you haven't had a chance to check them out before. Any recommendations/advice on this? Thank you in advance.
