I'd prefer an automatic box, but will resort to a top loading box like the Clever Cat. My kitties use World's Best cat litter in the booda clean step currently. The male pees down the side (so the pee clumps are caked on the side) of the box and weighs in at 13-14lbs (not fat). The female has perfect poos and pee clumps and is 10 lbs.
I'm not too bothered by noise, but I would be very bothered by smell if it gets ingrained in the unit. I try to clean out the boxes twice a day. On the rare occaision like today that I forgot to attend to the box this morning, I came back to 6-8 enormous piles of vomit with cat feces. Not pleasant.
The dog climbs baby gates and is almost as small as the cats. There's also no place in the apartment to put the box up. Just gross.
Any ideas on which box would be best for me? TIA!
