Geez. I don't even see why people hire uneducated (on animals) people.. ._.
Cheaper? Less intrusive? Employers know that when it's the issue of animal welfare on hand, if they were to place workers, who know their information about animals, that that puts those employees in a state of power. Those employees can tell customers, for example, "Despite what my manager might say....don't give your pet blah_de_blah, it's harmful to them." Or something like that. Thus, the employer looses business. Employers don't like to loose business. Employers like money.
I placed an application to Petco, and PetSmart. On my PetSmart application, I acted like I knew nothing about animals. On my Petco application, I spilled out that I know a little bit about turtles, cockatiels, dogs, cats, hamsters, rats, mice, degus, chinchillas, hedgehogs, sugar gliders, skunks, horses, goats, donkeys...etc etc...
I scored an interview with PetSmart.
I didn't even HEAR a single word from Petco.
