Pet house with heating and cooling functions. Please check the dimensions in the photos! Purchased in 2023 from Cainz, but my cat hardly used it. My cat weighs 4.5 kg, and there's still room inside. Although it hasn't been used for a long time, animals have entered it a few times, so please be aware that there may be some cat hair. I've thrown away the box, so I'll be packing and shipping it as is.
