Hamsters are actually very clean and relatively smell free little furballs. We can help keep odour down, and complete enclosure clean-outs too by introducing a potty into their lives. There are specially designed potties on the market but you don't need anything fancy - an old coffee or large jam jar will do. All you need to ensure is your hamster can get in and out comfortably. It is best to find one with a flattened sides to prevent your little one going for a wee and ending up rolling around his cage covered in sodden potty litter! If you observe your little one closely over a few days after giving his enclosure a good clean out you should hopefully see he goes to one or more particular corners to do his business. Place your potty here with a pinch of two of soiled cage litter inside ontop of whatever substrate you will use for his toilet. I prefer chinchilla sand - make sure it is sand now not the much finer dust as this can irritate their little noses - but you can get proprietary hamster litter balls and even just some of your normal litter layer will do. If chinchilla sand is unavailable you can use children's play sand but make sure to roast it in the oven first to kill of any nasties and make the grains a bit smoother. Get oven a good constant relatively high temperature maybe 200 or 220 degrees centigrade and leave them in there for 10 minutes. Give the sand grains a good toss/shake on the baking sheet whilst hot and then place back in for another 10 minutes. Remember to allow the sand to cool thoroughly before storing or using
and that the sheet and sand will be hot enough to give you a nasty burn so be careful
Potties should be changed daily preferably and you will also see your little one have a "bath" probably before widdling in it. One of my little ladies always wakes up goes for a wash and a wee, and then comes to say hello, when I change hers. For those hamsters that really seem to like their potty baths I often give them two potties, one for rolling around in, tossing up into their oxters/armpits and another for toilet purposes. Messy boys often have one in each corner but gradually you can wean them down to just the one. I have tried this technique with gerbils too, never rats or mice sorry as I have not personally cared for these, but I can't see why it would hurt to try.
