THANKO Pet House with Heating and Cooling Please check the dimensions in the photos. It has a heating and cooling function. I bought it at a flea market for my cat, but my cat is over 6 kg and it seemed too cramped, so it didn't go in. Please check the applicable size for cats and dogs. Suitable for sizes up to 5 kg. Although it hasn't been used, the cooling sheet has some discoloration. The previous owner also only used it once. The motor for cooling and heating makes noise periodically. According to the previous owner, it was purchased in the winter of 2023. There is no instruction manual. It hasn't been used for a long time, but since an animal has been inside once, I think there may be some animal hair, so please be aware of that.
