Our collection is ~120 herps. Too much work to list it all but ~70 snakes (12 boids, balance are colubrids), 10 lizards, 18 turtles plus some frogs and one salamander. We buy all of our rodents, which works out to over $3000 annually. Other costs, who knows? Probably close to $10,000 a year in total for direct animal related costs, but I'm guessing. It's all a write off for us though, as reptile education is our business...
