Have a 20lb cat, this is the biggest box I found that was visually appealing, However my cat urinates out of side entry and kick out litter. Was able to buy top entry litter liner and cut it higher than front entry plastic side and that worked. Loved the look of the box and how easy it is to clean.
Tray Liners - Type G (3-pack)
I currently have 2 modkats, they work perfectly and My cats can’t rip through the liners! I just wanted to have extra liners so I can change them out more regularly if the need rises.
I purchased the tray litter box that fits the G liners several years ago and we have loved this box. My cats are high pee-ers and the plastic splash guard is just high enough to stop it, but pee would still leak between the liner and tray. I did not realize they had redesigned the liners and tray box until I received this latest shipment and I really like the new design the way it fits over the top instead of being hooked on by the metal eyelets. I think this will go a long way and preventing leaks.
