Cats Living Inside and Outside

The luxury of cats being able to peruse both indoors and outdoors can sometimes bring risks. Do you have the appropriate precautions in place to ensure safe environments and a healthy life-style for your cat?

Many cat owners choose to provide stimulating indoor environments complete with climbing towers, areas to scratch, and hunting simulation tools. Many other cat owners choose to allow cats to also explore the outdoors, as it is their natural environment, according to Ken Lambrecht, DVM, of Westside Family Pet Clinic in Madison, Wis.

“Although controversial in terms of dangers to cats and songbirds, many people feel that as the cat is originally an outdoor creature, a hunter and only partially domesticated, that it truly needs the outdoor experience,” says Dr. Lambrecht. “The outdoors as their natural environment can be beneficial to allow them more natural activity and to burn calories.”

Cats that remain indoors are safer for many reasons. If your cat must be outside at times, take precautions. Dr. Lambrecht explains enclosed outdoor play areas and runs can be constructed for cats. He advises any cat that travels outdoors should have a microchip. Harnesses and quick release collars with tags provide other options to cat owners. According to Dr. Lambrecht, a new technology is currently evolving towards cat-sized wearable GPS technology. In this developing technology, when a cat travels outside of a certain geo-fence, an alarm would be sent to the owner’s smart phone. If allowing your cat to be outside, ensure your cat is spayed or neutered.

There are other measures cat owners can take to ensure their indoor-outdoor cat stays healthy. Because cats can bring in fleas, internal parasites including roundworms, and ringworm, certain health measures should be taken, states Dr. Lambrecht.

“Medication that provides good prevention against these parasites that also protect against heartworm is available from your veterinarian. Consumers need to be careful as some over-the-counter products are ineffective and dog products, if accidently used on cats, can be deadly,” he explains. “Heartworm disease is transmitted by mosquitoes, so any cats outside should have heartworm prevention prescribed by their veterinarian.”

Dr. Lambrecht notes that cats may bring home prey, such as mice, that owners should be prepared for. If multiple cats are in the household, cats can also bring in scents from outdoors other cats in the household will notice but should not cause a problem.

With winter quickly approaching, owners should keep a close eye on temperatures, wind conditions and other weather variables. Dr. Lambrecht suggests watching the body language of your cats as they will usually let owners know when they are ready to come inside.

“Short stays outside in an enclosed pen or harnessed on a leash are the safest ways to allow a cat outside,” Dr. Lambrecht clarifies. “Anything below 20°F and especially low wind chills should be watched closely. Sheltered areas close to the house and enclosed would be safest.”
