"A straight up letter of total frustration, following the advice of standard veterinary care" (watching an animal deteriorate)
Erica from Massachusetts writes "My 10-year old male cat (neutered) had a one-time, first-ever urinary tract blockage a year ago. I had been feeding him a commercial, mostly grain-free diet (both wet and dry food). We are not sure what precipitated this blockage, and thankfully it has not reoccurred. But since then, as a precaution, the vet recommended keeping him on the prescription Science Diet or Royal Canin acidifying formulas. I know how bad commercial pet foods are, and I hesitated keeping him on these crappy commercial food brands for an extended period of time. Sure enough, over the past year, I've seen a deterioration in his energy levels and vigor. Furthermore, he seems "addicted" to food now, almost grazing on kibble non-stop. Fortunately, he's able to go outside during the day, and therefore he gets a decent amount of exercise, fresh air and sunshine, and the occasional rabbit, mouse or bird that he catches. He used to be an astute hunter who would disappear all day, but now he seems to have lost a lot of his enthusiasm for hunting, and is more content to spend his day sleeping on the porch. Maybe he's just getting older, but I can't help but think this crappy diet that we've had him on is contributing to his lack of energy."
