Nope, they eat and crap like a cat or dog, but they don't smell nearly as bad, and they are sorta shy when they relieve themselves. I've got Rigor trained to go outside in the summer, through our kitty door. Mortis,,, well lets not talk about him.... sorta sad. I am patiently waiting to ummmm well bid him farewell probably any time, he's not doin' good at all. I think they had a mistake on him, or Rigor did alot more damage than I first thought.
They don't take batteries after they are out of their pack. Those batteries are for monitering health, and injetcing small sustinence fluid when needed. I've heard they still can legally sell these in Canada. I had to do a bit of around the corner, under the table sorta stuff to get mine, that;'s why I never returned Mortis to begin with.
You can order special food for them, but it's not necassary. They'll eat canned dogfood, catfood, or most human food. One thing they don't like are things like apples, or harder fruit like that. Raw potatoes or carrots and things of that natuer they seem to not like. I think their jaws aren't very strong, as these go to kids alot of the time. The best thing is they don't have to eat often. Mortis, I make eat a few spoonfulls of Fancy Feast at least once a day, and I have to make him eat it. Rigor, will sometimes getin the cupboards, but I've beat him for it once after he spilled a bag of flour all over the counter and floor, and he's not even hardly got on the couch after that. They seem to be pretty intelligent, and learn very quickly.
The thing is, Rigor's life-span is supposedly shorter than Motis's, so if Rigor lasts a year or two more, it won't be too weird having a Rigor, but not a Mortis. I have a feeling I won't be getting any more, as it was a huge run-around, and more money than I can shell out these days.
I want to take Rigor for a moped ride, but my daughter freaks out at me just mentioning it, so I haven't..... yet! hehehee
