The use of UV light is beneficial to the overall health of many different types of pets – some of which may surprise you! Learn more about what pets can benefit from UV light by reading the Avian & Exotic Animal Hospital of Louisiana article below.
Many reptiles and mammals benefit from exposure to UV light, including:
- Turtles
- Turtles
- Lizards
- Birds
- Rabbits
- Guinea Pig
- Chinchillas
Reptiles
Although snakes get enough vitamin D and calcium from their diets, other reptiles, such as turtles, tortoises, and lizards do not. Reptiles need the help of UV-B radiation to produce vitamin D3 in their skin to absorb calcium from their food—which is directly related to the strength of their bones. And if they are not given the necessary exposure, they can develop nutritional metabolic bone disease, which can be fatal if left untreated.
However, even reptiles that do not require UV lighting still benefit from low levels of exposure. For example, studies have shown that leopard geckos can live perfectly healthy lives without being exposed to UV lighting, but they seem to thrive if given the chance to get low-level exposure for 15 – 60 minutes per day. Most other reptiles seem to benefit from 2-4 hours of UV light per day.
Additionally, reptiles have special scales on top of their heads called “parietal eyes.” And the retina in this “eye” connects to the area of the brain that produces melatonin and serotonin. Thus, appropriate lighting is essential when maintaining a reptile’s mood. This light also stimulates their appetite, maintains their immune function, and regulates their body temperature.
A UV light source should emit light in the UV-B range, which is 290-320 nanometers. Most lights can emit both UV-B and UV-A lights, but UV-A light (320 to 400 nanometers) does not produce vitamin D3 in the skin like UV-B light does. (although UV-A exposure may still be important for a reptile’s behavior).
The following UV lights have been researched to emit proven levels of UV:
Note that lights dull with age and will likely need to be replaced every 6 months (or as directed by the manufacturer). UV lighting is only effective if it is within 12 inches (30 centimeters) of your pet. UV light is blocked by glass, plexiglass, or any other filtering material, so your pet must have direct exposure to light.
Different species require different UV light settings or wattages, so if you’re not sure what lights and amount of exposure (known as “photoperiod”) is best for your pet, please consult a strange vet.
Birds
Birds
It was discovered that the bones of indoor birds are not as strong as those kept outdoors. So, exposure to the right level of UV lighting can also benefit them. In fact, UV lights are specifically designed to help reverse severe cases of injury, arthritis, and weakness. However, owners should be careful to monitor UV lighting levels because if it is too high, it can cause burns and cancers in your bird.
When setting up lights, you should provide a “gradient,” so that there is space in the cage away from the light, and your bird can go there if they want. The high output light must not exceed six inches (15 centimeters) and the low input light must not exceed 12 inches (30 centimeters) from the top of the bird’s head at the highest perching point.
Mammals
Rabbits, Guinea Pigs and Chinchillas
Like birds, indoor guinea pigs, rabbits and chinchillas don’t have bones as strong as outdoor ones. So, UV lights can be beneficial to them as well. For example, animals with broken legs experienced an increase in bone density after exposure to UV light.
You want to keep the light at least nine inches (about 23 centimeters) away from your pet’s cage. UV exposure is recommended for 2-4 hours per day.
The Sun is Superior
It’s clear that animals benefit from exposure to UV lighting, but even the best bulbs aren’t as good as natural sunlight. Consequently, providing a supervised and safe outdoor space for your pets will also improve their bone health and overall well-being.
***If you decide to spend time outside, make sure you put your pet in a sturdy cage to prevent your pet from escaping or from a hawk, cat, or dog from attacking your beloved pet***.
Ask Our Exotic Vet If You Have Additional Questions About UV Lights and Your Pet
Reptiles need UV light to survive (without it, they develop serious, fatal diseases). And some mammals have been found to benefit from it as well. However, specific lights and exposure times should be discussed at length with an exotic veterinarian.
Moreover, time in natural sunlight is better than any artificial light (or light filtered through a window), so you should arrange for regular, supervised time outside. Of course, make sure you take the necessary safety precautions.
If you have any additional questions, please be sure to let us know the next time your exotic pet visits us at the vet. To schedule an exam of your exotic pet, call the Avian & Exotic Animal Hospital of Louisiana at (504) 455-6386.
