I purchased this from a home center in November and set it up in November, but since my cat prefers open spaces, as expected, they hardly used it, so I'm putting it up for sale. I think this would be good for cats who like dark and enclosed spaces. My cat is 4.5 kg, and judging by the size of the kotatsu, it seems like it would be a good fit. I hesitated to wash it since they only went in briefly a few times, but I didn't wash it because of the scent. The new product smell still lingers a bit. I used a lint roller on all the fabric to remove any fur, but please understand that it was kept in a room with a cat. It's almost new, but it has been opened and set up, so please consider this before purchasing.
