1)     While I understand that the park’s onsite geologist may not be an animal expert, ferrets are not rodents and saying as much makes me think you need some more basic education. A likely analogy would be me calling water or oil a fossilized rock! I mean, they both come from the ground, right?
2)     This is just another example of why pet stores should not be selling any kind of animal. And I want to know what cashier let this person walk out with this assortment of animals? None of these things should be sold at the same time! Their habitats are totally different and the likelihood that the person who bought this weird assortment of animals would have four very distinct habitats set up is highly unlikely. Hopefully they will ask the local Petco to see if a clerk recalls selling these animals and we can determine who the individual is that did this is.
