Question:
I recently read your column on pop-top canned cat food. My friends who are cat owners say I'm nuts. They feed their cats popular store-bought canned cat food with pop-tops and have no problems.May I please have your response regarding this issue? I love my two cats and have had them (they are sisters) since they were 2 years old.My vet says they have either kidney or liver disease but thinks the pop-top canned-food warning is nonsense. I believe it's either the food or flea spray that's harming them. Your love and kindness for our pet families is deeply appreciated.

But, as I am aware of what goes into many brand-name commercial pet foods, I offer my own pets basic, home-prepared diets, available on my Web site at www.doctormwfox.org. Some quality pet foods are on the market, but reading the labels can be misleading at best.Many factors can contribute to feline thyroid disease in addition to the chemicals lining the pop-top cans - notably, retrovirus infections and hormone-disrupting chemicals called dioxi
