I was wondering if those with large collections of herps, is there more of a smell? Maybe you guys don't notice, since the nose gets used to it, but I'm asking those that maybe visited large facilites...has there been a smell?

I visited Reptile Depot and Prehistoric Pets here in South Cali, and they both smell. Now I'm wondering is it because they're not cleaning the cages, or is it...the more animals, the more smell?
