this litter box injured my kitty.   i noticed her back kept getting scraped up and realized there was a very sharp jagged edge on the backside of the plastic top strip and apparently when she’d go in the box she’d scratch her back. and she’s a very small cat so it wasn’t her size that was a problem.   it was sharp when i ran my finger across it.   Sadly i didn’t realize at first how she was getting scraped.  her wound got infected and she needed antibiotics .   i could tell it was painful for her 

i do not want to see this happen to another kitty again or have someone else incur unnecessary vet bills. 

Wayfair refused to let me return it because it was past 30 days.  I’ll think twice before ordering anything from them again
