Can anyone recommend a heat pad, please?

I'm thinking of getting one for FizzyCat who is 15 (and a half!) and spends a lot of time on the back of a sofa just above a radiator now the weather has turned colder. Do the self-heating ones work well? Microwave ones? Electric ones? Thanks for any info.

I have had the self heating ones, which seemed to work well, and also this one from Amazon, which went down very well, my old cat loved it!

Thanks, maybe!

I just bought an electric blanket for the big bed and leave it on. Seniorboy has bad arthritis and likes to lie 'long' in the heat. (And I can share it as well. )
