Are use fancy pants for pets for my severe CH cat who couldn't hold it when he had to go to bathroom used to use the litter box then he stopped but then he kept going downhill sadly he only made it to 9 months but the diapers were a lifesaver and they're made to fit
I have litter boxes that are cut down and for my severe CH cat I bought a thing to mix cement it's bigger than a litter box and he has more room to go to the bathroom and getting around Less mess
