Asparagus fern (also called emerald feather, emerald fern, sprengeri fern, plumosa fern, and lace fern) is toxic to dogs and cats. The toxic agent in this plant is sapogenin—a steroid found in a variety of plants. If a dog or cat ingests the berries of this plant, vomiting, diarrhea, and/or abdominal pain can occur. Allergic dermatitis (skin inflammation) can occur if an animal is repeatedly exposed to this plant.

Heartworm disease is a serious and potentially fatal condition that affects dogs, cats, and up to 30 other species of animals. It is caused by parasitic worms (heartworms) living in the major blood vessels of the lungs and, occasionally, in the heart. These worms are transmitted (as microscopic larvae) through the bite of an infected mosquito. The scientific name for the heartworm parasite is Dirofilaria immitis.

A high-quality, complete and balanced diet is important for the health and longevity of your dog. Among other benefits, a proper diet helps build strong bones, promotes healthy gums and teeth, protects immune function, and results in a lustrous haircoat. Unlike cats, which are carnivores (meaning that they must eat meat), dogs are omnivores, meaning that they can eat meat and plants as their primary food sources.

One of the most common pet lizards, the leopard gecko is hardy and friendly. It can vocalize, lick its eyes, and “wink” its ears. Leopard geckos have various colors and patterns, and their price varies according to their appearance. Housing and feeding a leopard gecko is relatively simple, but some guidelines must be followed to keep these geckos healthy.

Obesity (the storage of excess fat) is usually caused by excessive food intake and insufficient exercise. One of the biggest problems in cats is overfeeding, which can lead to serious problems, including obesity, heart disease, and arthritis, resulting in a shortened life span. Your veterinarian can recommend a proper type and amount of food to maintain your cat’s ideal weight.
