I feed my dog Pepper raw food and some cooked. We adopted her 14 1/2 years ago when she was 2. Her blood tests were poor - she had problems with almost every part of her body, breathing, heart, digestion and kidneys.
My son's adopted cat Cheddar, 2 years old now, is mostly on raw chicken. He used to have seizures when he was a baby. It could have been caused by an injury to his head before he was brought into the shelter, or / and the toxic food, vaccines. Cheddar is good now and has a great life having access to our backyard.
