Those of us who have pets know the benefits of pet ownership. There's just something very physically and emotionally positive about owning a cat or dog, and the research literature is full of proof.

We generally have lower blood pressure because pets reduce stress and anxiety. Maybe it's the soft fur to pet, the funny antics or the happy welcome when we come home, but we're happier and better able to fend off depression. We're also in better shape, more active and physical, because of the care we need to give: walking, throwing toys, feeding, bending to put down food and water, daily brushing.

Limited incomes can come into play, however. If you have a pet but are considering giving it up because of the cost of pet food, wait. All across the country there are local groups that can help you keep your pet. Some will help financially if the cost of food is too much. Others will help with the cost of veterinary care. One group will even take care of your pet if you go into the hospital. Other groups will match seniors with pets and provide help.

If you receive Meals on Wheels or another program, they often have pet food they can deliver too. Your first calls should be to the local humane society, the pet store or the veterinarian: They're the ones most likely to know about programs available in your area. Or go online and search for "pet food assistance" and put in your town and state.

If you don't have a pet, consider starting the New Year with an adult pet that's outgrown the puppy/kitten stage and needs someone to love. It will be good for both of you!
