Are laser pointers safe? My cat really goes crazy when I get his out to play.

As with so many other things, I have to give an answer and a caveat.

For many cats, laser pointers are wonderful for getting a good workout. For indoor cats, especially, pretty much anything that gets a cat moving is a good thing.

But for some cats, these toys have been blamed for the development of compulsive behaviors, such as excessive grooming.

The worry most people have regarding safety is about the laser itself. Of course you shouldn't shine the light into your pet's eyes (or your own) on purpose, but you don't have to worry if the beam hits an eye for a split- second in play.

The potential problem with these toys comes because the cat can never "win" the game. Even if the cat catches the moving dot, there's nothing there. The cat gets all worked up with no resolution – every time. Even in the wild, a hunting cat will catch the prey now and then. But there's no catching that alluring, fast-moving red dot!

Although most cats will wind down from a hunting high with no harm done, some will redirect their frustration in ways that can hurt themselves or others.

There's an easy way out of the problem. After you've used the laser pointer to exhaust your cat (up and down stairs can be fun), switch to a toy that can be caught and "killed," such as on the end of a fishing pole, or a stuffed mouse.

Your cat can then wind down with the satisfaction of having won the game, with "dead prey" to show for his hunting prowess.

The buzz

• Rats can be clever, playful and affectionate pets, perfect not only for responsible older children, but also for open-minded adults.

When purchased or adopted from reputable sources and kept in good health, these pets usually live two to three years. Domesticated rats come in many colors and patterns, and can learn tricks as easily as many dogs.

• Raw vegetables and fruits are a wonderful treat for dogs. Veterinarians often recommend carrots and apple slices as a substitute for commercial treats, especially for dogs who are pudgy. (Another easy weight-loss trick involving vegetables: Substitute thawed green beans for part of your dog's daily food ration. They'll make your pet feel full without adding much in the way of calories.)

Not all fruits and vegetables are good for your dog, though; some may be toxic. Absolute no-no's include raisins and grapes, avocados, onions and many nuts.

When in doubt, ask your veterinarian or visit the ASPCA's Animal Poison Control Center online (www.aspca.org/apcc).

• We all know yawning is contagious among people, but dogs can also "catch" our yawns.

When dogs yawn on their own, they're likely doing it in an effort to relieve stress than to signify naptime is near.
