I think that guinea pigs aren't naturally flexible enough to clean themselves to the extent that rats do? :lol:
Also, the size of the cage has a lot to do with how often it needs to be cleaned. And what type of cleaning agent is being used.
When my Noodle was in his smaller cage, I cleaned it about once weekly. And in the beginning, when I did wash off
everything, I noticed he would mark things all over again. When he became used to the cage as his home, he stopped doing this, and regularly used one specific spot to do his business.
Now he is in a ferret-sized cage with a young female [[don't worry guys- he's neutered]] and I have to clean it every four days. Just wipe down the platforms with my Cage Spray, maybe change the litter from the litter box. But this is all because of Olive, because she is new. I am very confident that she will learn where the box is, and learn to navigate the huge cage soon. Noodle takes good care of her. And then, I will probably be back to wiping things down once weekly.
Also, lacy_black, I just gave them baths yesterday... Since adding Olive, Noodle has been 'claiming' her, and they sleep together, so they were kind of smelly. Noodle acted like he enjoyed himself though. I did assume that rats would have similar
bathing needs to cats- rarely, if ever. I guess I was right on that? I did get a "tearless small animal shampoo" and avoided their faces getting wet or shampoo'd at all.
