Cat and dog nutrition: what to feed and what to skip.

Q: Is wet or dry food better for cats?

Both can be complete. Canned food is at least 75% water and dry food 6% to 10%, so wet food helps cats drink enough. (Source: Cornell Feline Health Center)

Q: Can dogs eat grapes?

No. Grapes and raisins can cause kidney damage in dogs. Call your vet or ASPCA Animal Poison Control at (888) 426-4435 if your dog eats any. (Source: ASPCA Animal Poison Control)

Q: How do I compare wet and dry food labels?

Remove the water first. Divide the nutrient percentage by (100 minus the moisture percentage) and multiply by 100. The Food Finder does it for every food. (Source: Merck Veterinary Manual)

Check the food, not the bag

The Food Finder puts cat and dog foods on the same scale, with the water removed, so wet and dry foods compare fairly.

Open the Food Finder

The dry-matter formula

nutrient % ÷ (100 − moisture %) × 100

Example: 10.5% protein in a can that is 78% water is about 48% protein once the water is removed. Formula: Merck Veterinary Manual.
