I've been debating getting one of the Litter Robots ever since a friend showed me hers. My most hated chore is cleaning the litter box -- I've probably tried them all. I've been known to throw out boxes rather than clean them. I had a Littermaid for a while, but threw it out when I moved; the cats liked to attack it when it moved, anyway (the first time it started, my spooky cat was in the room -- it took her a while to stop staring at it like it was a monster). I currently have an OmegaPaws, which seems to be a manual version of the litter robot, but I'm even bad about using that properly.
All that said, I have two questions.
1) Do you think the LR would be large enough to handle my cats? One's a good-sized 14-pounder. The other is a fat 15-pounder (delicate bones, but a definite loaf kitty.) Both seem to be able to use the smallish OmegaPaws, although the 14-pounder's head does stick out. I haven't see the 15-pounder use it, but she's a spooky girl and is scared of the dog so waits for the dog to go to bed (with me).
2) Would the unit get ruined if it were set outside (ie, on a covered, fenced-in patio). I'm getting ready to move to a smaller apartment, so I'll be losing my spare bathroom, and I was contemplating putting it on my patio (or in my outside storage closet) after I fence it in. I live in Houston, so it's very humid here. I'm not sure how the electronics and wires are protected.
I especially like the height -- my papillon enjoys raiding the litter box far too much. Since he's smaller than the cats...
Thanks!
