Got it fast. Thank you seller. I did. I put a warm litter on top. Young Cats looked like they were, but they didn't risk getting in. Wait!
It is superb but I can not use it because the fabric is made of meshes in which my little rabbit could get stuck with claws (only the fabrics of solid colors) so I took 1 with a patterned fabric that seem different
Although it took a while to get here, my cat absolutely loves it. The quality of the material is also very good and is as described.
