hi! i have been using the kaytee bedding for my pigs litter box and i find that it just gets really gross like sticking to the bottom and doesn’t absorb all the way. is it better to use bedding or shavings for the litter box? also i have heard of the litter pellets? i use a pretty big cat sized litter box and emptying it out every 2-3 days has become expensive with the kaytee bedding. also is it better to use a hay bag or just pile the hay on one side?
