Since we moved to Florida, we no longer have a basement - I really miss that! Also, I have had nothing but problems with indoor cats here - we ended up with several that do not use the litter box, so I have had to be super-vigilent about keeping the litter boxes clean and making sure they are accesible. Had to get rid of all rugs and they even ruined a couch. The worst offender was put back outside, but that left me with one who is questionable around the furniture, so I have covered the new couch with a waterproof mattress pad and a slipcover (sucks!). Unfortunately, the feral kitten I rescued has recently decided that the couch is his litter box - I am at my wits end. He never had an accident from December when I brought him in - I thought he would be fine, but this weekend I caught him twice peeing on the couch. I scared him away and immediately put a new cover on the couch and washed the soiled covers on the “sanitize” setting of my washer, but the next day he did the same thing. Now I have to keep him locked down the other side of the house and pray he does not decide to pee on our bed or somewhere else. Sorry to vent, but I am at my wits end. Wish I was back to 2 or 3 kitties that did not have these issues. I have 5 - 2 of which are a problem and a 3rd that goes on the tile beside the litter box instead of in it. But I digress…
We are planning to re-model our master bath, laundry room and closet area, and I plan to do a setup similar to Gray Horse - I will put a tile floor (possibly with a drain) in the laundry room or possibly in a separate utility closet and will put the litter boxes in there with a small access door that the dogs can’t get in, or possibly a baby gate (my chihuahua could get through the access door).
I like those fancy furniture-like cabinets, and I like the sterilite container idea, but mine are in an unused bathtub down by my office. Yuck, but easy to clean now until we remodel.
