  • Erythromycin is given by mouth or injection and is used off label to treat bacterial infections and gastrointestinal motility problems in many animal species. Common side effects include diarrhea, lack of appetite, and vomiting. Do not use in pets that are allergic to it, have liver disease or dysfunction, or in pets such as rabbits, gerbils, guinea pigs, or hamsters. If a negative reaction occurs, please call your veterinary office.

  • Erythromycin ophthalmic is an antimicrobial medication used to treat certain types of eye infections. It may be used “off label” or “extra label” to treat other eye conditions. Erythromycin ophthalmic comes in ointment form. Caution when using this medication in pocket pets as fatal diarrhea may occur if ingested orally.

  • Esafoxolaner + eprinomectin + praziquantel is given topically on the skin to treat and protect against various internal and external parasites and prevent heartworm in cats. Side effects are rare but may include hair loss at the application site, gastrointestinal upset, skin reactions, or neurologic signs. Use caution in sick or underweight cats. If a negative reaction occurs, please call your veterinary office.

  • Esophageal tumors are extremely rare but more often than not malignant type tumors. The cause is unknown but cases in tropical environments may be due to infection by the worm Spirocerca lupi. Treatment options are limited as surgical complications are high due to the advanced nature of the disease at time of diagnosis.

  • Esophagostomy tubes are placed through the skin of the neck into the esophagus to enable ongoing nutrition in cats that either refuse to eat or are unable to chew and swallow food. A diet will be recommended by your veterinarian but must be liquefied with water before it can pass through the tube. Medications can also be administered through the tube. Step-by-step instructions are provided. The decision to remove the tube will be determined by your veterinarian.

  • Many liquid potpourri products and essential oils, including oil of cinnamon, citrus, pennyroyal, peppermint, pine, sweet birch, tea tree (melaleuca), wintergreen, and ylang ylang, are poisonous to cats. Both ingestion and skin exposure can be toxic.

  • The estrous cycle, better known as a female cat's heat cycle, consists of several stages; the stage called estrus refers to when the female is sexually receptive. This handout explains the age of onset, the clinical signs of a cat in heat, the length and phases of the heat cycle, as well as the benefits of spaying a female before her first heat cycle.

  • Ethylene glycol, a sweet-tasting, odorless liquid, is the active ingredient in antifreeze. Ethylene glycol can also be found, in lower concentrations, in some windshield de-icing agents, hydraulic brake fluid, motor oils, solvents, paints, film processing solutions, wood stains, inks, printer cartridges. Ethylene glycol is poisonous to cats; immediate treatment is essential.

  • Open and honest communication with your veterinarian and veterinary healthcare team throughout your cat's life lays the foundation for effective communication when that cat's life begins drawing to a close. Discussion with your veterinarian will clarify any specific medical implications of your cat's disease that can serve as benchmarks to suggest that euthanasia should be considered. Most often, euthanasia is provided at the veterinary practice or in your home. The veterinary healthcare team will be an important partner as you negotiate the difficult days and decisions leading up to your cat's peaceful passing.

  • Losing weight can be difficult. While feeding a prescription weight loss diet is certainly a good start in a weight loss program for your cat, it is important to remember that food intake is only one part of the problem; energy expenditure is also significant. Encouraging your cat to exercise by playing with him, putting his food in unusual places so he has to look for it, and making him work for his food (e.g., training, foraging toys) will help.
