Actually, they have 14 hamsters. We try and segegrate them and they each have several Habitrails but we have a glut of hamsters - they like to breed. We give them away and they occasionally die but we seem to maintain anywhere between 10 and 20 hamsters at a time. My question may be considered strange. When they die, about once every other month, roughly six times a year, we bury them in the garden. We bury them loose in the garden, not in any sort of enclosure or crypt but dig a hole about 2 feet down and plop them in. It is very respectful but it happens quite often. I grow green beans, tomatoes, green peppers and turnips. Is there any risk to my food supply created by this burial method. I would say over the last 3 years, we have disposed of roughly 25-30 carcasses this way. My garden is very vibrant and I get a lot of compliments on my tomatoes ("Juiciest on the planet" says my neighbor). We haven't gotten sick or anything but I am wondering whether the ground will attain a critical mass at some point.
