Review on Cozy & Waterproof Dog Blanket For Larger Breeds - Self-Warming, Washable & Snuggly Soft Terry Sherpa In Silver Gray - Furhaven Large Edition by Dan Quiceno

I read many of the reviews and I believe some people didn't understand "self warming". This is not like a heating pad - the bed doesn't warm up. The cats body heat is reflected back up into their body to keep them warm.I have a 19 ye old cat who has always been tiny with no body fat so I got her a small one. She loves it since she can lay in the window again. Having that extra body heat reflected back into her helps her get up and walk easier with her arthritis.When she wasn't on it, my younger 9 yr old cat stole it and wouldn't lay in his favorite bed anymore. So I got him the large size and put it on his bed. He is using his bed again.My 3rd cat is new to the family and stretches out when he lays. No cat bed holds him. So I got him one of these to coax him to sleep where I have room for a bed. We'll see if it works or not.I also bought 2 more small ones to fit on the 2 window seats. It is cold there but all of the cats love laying there watching the neighborhood and soaking up the sunlight. These self warming blankets are great there. The side laying on the blankets is warm and the sun keeps the upper side warm.As for the crinkling noise, most cats don't mind it. Kind of like the toys that make the same noise. Every self warming bed is going to make this noise.
