I have an extra bathroom which no one in the house uses; we put our cat's litter box in it. I love cats a lot so I was thinking, if I ended up adopting a lot of them (being able to take care of them all of course) can I use the extra bathtub, if sealed really well with a bath plug, as a litter box? I'm thinking of filling it with a lot of litter so it won't need changing for at least 2 months or so.
I won't allow guests to ever see it and I will make sure to seal it really well with a bath plug. What are the positives and negatives of having a bathtub as a litter box, if cleaned daily?
