Review on Modkat Litter Tray, Includes Scoop And Reusable Liner - White by Jose Wititsuwannakul

I have three maine coon mixes and one is sadly overweight, but he has FLUTD and so when he goes into the box his bottom is against the wall *in this scenario with the box there is no wall* and pees over the side. I had thought this would be higher, but the front is not as high as I thought. I also thought it would be much larger. It's smaller than the other box I had that he was peeing over the edge (i mean the front dip part). I will give it a go, seems fine for the smaller cats but the three big boys not so sure if they can comfortably use this without going over the front step.
