I have 3 piggies..2 girls, 1 boy but he is neutered. I have heard that sometimes intact males have a smell and need their glands cleaned..I use shavings and do a complete replace every2 - 3 days, and they are in a 2X4 cage. About every other month a will give them a bath. These will probably be my last piggies because of the expense. Between the litter, hay, piggie food, vit.C tablets and lettuce, veggies ect they are not a cheap pet. I think my birds are a little cheaper so I think I will stick to them and my dogs. Plus as I get older I really need to start cutting back. I've had some sort of small animal since I was in 3 rd grade and I'm 58 now. Piggies are rescues...they are about 3 1/2 now..
