Excellent product!
My cat has been quite anxious recently because he had a major surgery about 3 weeks ago and I bought their started kid in order to make him feel at ease while I am away and with him at home. I tried it last night with him and after plugging it in for about an hour my cat was way more relaxed. He stopped swishing his tail, and he went back to being really sweet with me. There was no overheating, it was perfectly warm, but I installed it in a way where the bottle of the liquid is hanging from below the diffuser itself. Overall, highly recommended for single cats.
