When I went to bed last night we had three inside cats - Bug, Kitty and KiKi and one outside cat - Cuatro. When I woke up this morning we had four inside cats, zero outside cats. Cuatro snuck in on DH when he was leaving for work and he didn't bother to put her out. I put her out when I got up and she snuck back in when I came home from the feedstore. Apparently Cuatro walks where even the devil wouldn't dare, between the legs of our two german shepherds when we are letting them out. She blends in real well. So Cuatro is asleep on the couch where she's been all afternoon. I just overheard DH telling her that if she's lucky mama will let her stay in all night. Tonight's low is supposed to be in the low 30s. I need to know something. Bug realized where the litter box was by following KiKi and Kitty. Will Cuatro also know where the litter box is? I tried showing her, but she ran out of the bathroom like her tail was on fire. I'll have to get another litter box this week, what with four cats and the elephant that I'm sure sneaks in during the night to use it. PLEASE NOTE: Imp, your input on this matter is not needed.
