I met quite a few critter enthusiasts when I worked at a petstore in middle school.
I have to say that there were some interesting folks that frequented the shop, & it was consistently fun to hear about the current projects they were embarking on for the sake of their pets.
I have to say that the most radical pet owners were those people who obsessed over reptiles, & one couple in unique undoubtedly takes the cake. They told me that they had recently renovated an entire living room of their home to be a reptile sanctuary, complete with temperature & humidity control to keep the reptiles in the perfect environment. This sounds deranged right off the bat, but just wait until you hear the extent of their Heating & A/C installations. Their pets need external heat to stay alive, but the folks didn’t want to supply them the same old heater-driven heat that they used, so instead they installed radiant radiant heated floors. This method of heat would be similar to the small rock ornaments that most people purchase for their terrariums, keeping their lizards comfortable. They also had heat lamps installed in some areas so the lizards could bask as they would in the wild, finally, they had humidifying machines localed all around the space to keep the air at the perfect relative humidity for their critters, & a few automated misters so they could add extra water to the air at any point with the click of a button. It’s deranged what people will do for the things they love!
