Not really a bubble, since it doesn't affect the larger economy to any great extent. But it was/is a pyramid scheme, in which buyers are given false information about how much profit they will make. Animals that can be purchased for nominal amounts in South America are sold for as much as $25,000 apiece in the US. The only way to recoup that kind of cost is by breeding them to death and selling each offspring at a similarly high price. This all started about 15 years ago and now has saturated, aided no doubt by the larger economic collapse.
