Chinchillas are soft, quick and full of energy, and with good care they can be with you for many years. Two of the biggest threats to their health are dental disease and overheating. Both are largely preventable, and Middle Tennessee summers make the second one especially important.
All of a chinchilla's teeth grow continuously throughout life. Constant chewing on hay keeps them worn to the right length. When the diet doesn't provide enough chewing, or when genetics or injury play a role, teeth can overgrow, form sharp edges or develop root problems.
Dental disease is one of the most common health problems in pet chinchillas, and it's usually hard to spot at home until it's advanced. Like rabbits and guinea pigs, chinchillas are prey animals that hide discomfort, and dental pain tends to be long-term pain. That's why a thorough dental exam is part of every chinchilla checkup.
The classic early sign is a wet chin or drooling. You might also notice your chinchilla dropping food, avoiding hard foods, or losing weight while still seeming to eat. Droppings may get smaller or fewer. Watery eyes can appear when tooth roots press on the tear ducts. Front teeth that look overgrown, or pale instead of their usual orange, are worth a mention at your next visit, as is any swelling along the jaw or a dull, hunched look.
Unlimited, good-quality grass hay such as timothy is the single most important part of dental health. Pair it with a plain chinchilla pellet rather than a mix with seeds, nuts, corn or colorful pieces, keep sugary treats to a minimum, and offer safe chew items such as untreated wood. Weigh your chinchilla regularly on a kitchen scale, since weight loss is often the first clue.
Diagnosis usually involves a careful oral exam under sedation and dental X-rays, and sometimes CT. Treatment may include trimming and reshaping overgrown teeth, treating infection, extracting diseased teeth, pain control and nutritional support. Dental disease often needs ongoing management with regular rechecks. I plan anesthesia for these small patients carefully, including keeping them warm from start to finish, and I've published on an anesthesia approach for chinchilla surgery.
Chinchillas come from the cool, dry Andes Mountains. Their fur is incredibly dense, which keeps them warm but makes it very hard to shed heat, and they can't sweat. A warm, humid room can become dangerous quickly.
Keep the room cool. Priest Lake Veterinary Hospital's care guide recommends temperatures at or below about 75°F, with low humidity. Keep the cage out of direct sunlight and away from windows, heaters and stuffy rooms, and have a plan for power outages or air conditioning failures in summer. A chilled granite or marble tile in the cage gives your chinchilla somewhere cool to lie. Never leave a chinchilla in a parked car, and plan travel for cooler times of day. Don't wet the fur to cool them down, because their coat dries very slowly.
Regular dust baths aren't a luxury. Without them, a chinchilla's dense fur holds oils and moisture, and that sets the stage for skin disease. It's a good example of a normal behavior that's directly tied to health. Offer a dust bath regularly, and never a water bath.
A chinchilla in trouble from heat may lie stretched out and limp, breathe rapidly or with an open mouth, have bright red ears, drool, or become restless and then lethargic. Collapse and seizures can follow. Heatstroke is a life-threatening emergency. Move your chinchilla to a cool, shaded spot, place them on a cool (not icy) surface, and call your veterinarian or an emergency clinic right away.
Seek care immediately if your chinchilla shows any signs of heat stress, hasn't eaten in about half a day, has stopped producing droppings, is breathing with effort, or is hunched and unresponsive.
Book a prompt visit for a wet chin, weight loss, dropping food, eye discharge, fur loss or a damp, matted coat.
