Material around cat hut part split and ripped after second day.  Have two cats who are rambunctious but still didnt expect it to have damage that so quickly, anyways, if at all.  It wasnt along seem it was 2 inches away from it and like a starburst Riphole with runs I noticed because one cat poked hole through it to look at me lol.  I tried sewing it but it keeps running and splitting like pantyhose now.  But otherwise super sturdy and obviously they loved it lol.
