I purchased a Petmate Igloo Cat Condo for a stray cat I have been caring for for 6 mos. or so. Note, if it were my decision, and not his, he would be an indoor cat. I am reading a lot of different opinions about what kind of bedding I should provide for warmth and comfort. I have been looking at self-warming heating pads and plug-in heated pads. But, I have also read that straw or small pet bedding wicks water better to keep the cat dry and keeps the cat warmer than either pad.. I'm not sure what to do. I could buy a pad and cover it with straw, but I am not sure the cat would feel the warmth though the straw. Any thoughts? Thank you.
