Everyone is telling me the first step to switching Patricia from dry to wet food is putting her on a schedule. She eats so little I would rather not. I just want to put her on wet food. Yesterday, I measured 1/4 cup of kibbles and she only ate enough to live another day. It makes me think if I switch her to a schedule, she will not get enough food. Would it be better to add wet to dry instead of switch from dry to wet to make sure she, at age 16, gets enough food every day?
