2. Know His Nutritional Needs
"One of the biggest mistakes owners make is leaving a bowl of food sitting around the entire day," says Walther. "A pet can graze as he pleases and consequently get overfed." Instead, ask your vet how much food your pet actually needs on a daily basis (or, at the very least, read the pet-food label) and divide this serving into two, feeding your pooch or cat half in the morning and half at night. And try putting your cat's bowl on a countertop, washing machine, or other elevated surface. Lazy kitties will have to jump up to reach it, a bit of extra exercise that might also dissuade them from nonstop munching throughout the day. If you opt for a low-calorie meal option, check with your vet first to make sure it meets your pet's nutritional needs.
