You'd be surprised - some cats are very finicky. There are two male cats at our shelter who share a room and require a total of 5 litter boxes. :lol3: They both require one to pee in and another to poo in, won't use each other's boxes (though they otherwise get along fine), and one doesn't like to use a "dirty" box. He's a senior and his bladder control isn't great, so the 5th box is for those times he can't hold it till somebody scoops his "pee box".I cannot believe that two or more need to be used for two cats (my fiance and I share one bathroom ) But I have a spare, so I'll try putting it back out today and see if this helps the problem at all.
Thanks!
