Were the pet meds cheaper or more expensive? We used to do a lot of self administered animal and livestock medication. When we did it, the animal stuff was generally cheaper but was the same stuff. If you remember the ivermectin and fenbendazole warnings that emerged during and after the Covid pandemic, there was all this stuff about not using the animal stuff on humans. They were the SAME med, although in some of those cases, the concentrations were different. You don't wan to give a 180 pound human the same amount as a 1200 pound horse.
