This article will cover some"semi-veterinary" things that you can do to help an aging pet increase mobility and comfort around the house. We see a fairly high percentage of elderly pets, and we are often impressed with some of the things owners come up with to help their pets as they age.

One of the things people tend to forget is the importance of keeping nails short. Long nails for cats or dogs make it harder to grip on slick floors and can even push up the toes and worsen arthritis. If you have trouble trimming at home make an appointment with your vet.

For large dogs with arthritis that are having trouble with hardwood or other slick floors, many will do very well if you can make them a "trail" of throw rugs or cheap floor rugs from room to room. Most large hardware stores sell cheap long thin carpets that you can use for this. Some rug stores will give you throw-away sections for free if you explain why you are asking. Prevent the rugs from slipping by buying some of the undercarpet liner most of the stores carry as well.

Almost all cats and many dogs will appreciate a heated bed as they age. Many options are available now, but most are a simple foam or padded bedding with a heat pad underneath that only heats to one temperature (usually around body temperature). A warm bed helps keep joints warm (especially in winter) and makes it easier to get up in the morning or after a nap.

Another help for large dogs are ramps if you have steps or a deck. These can vary from very fancy and professionally installed to do-it-yourself homemade ramps. I have built several ramps for our aging German Shepherd with plywood and nails from the local hardware store. I nailed roofing shingles to the wood to give her traction when it is wet. Pay attention to the angle of the ramp. If it's too steep a pet may not have the strength to ascend the ramp.

Many aging cats are finicky about eating and drinking. Many cats seem to prefer running water for drinking, especially as they age. Drinking fountains give cats a source of running water that can be cleaned as needed.

As with ramps these range from very basic versions -- a very small aquarium pump in a bowl -- to commercial brands that can be very elaborate. For any fountain made or bought make sure that the materials will not leach anything into the water over time.

Most of these tips are very simple but can make a big difference in the daily life of an aging pet.
