Can high fat diets cause cataracts?
================================
by LisaThis article is actually a composite of discussions held with several veterinarians, an animal nutritionist, and a couple of other breeders. There's not much research done in this area, but there's a strong concurrence of opinion surrounding a condition that appears to be much like cataracts.
Unfortunately many people mistake the condition to be cataracts when they are really dealing with a nutritional issue that is highly controllable. It is often dangerous for us lay people to confidently diagnose our own pets because sometimes what may appear to be one thing may in fact be something completely different.
Are your gliders' eyes cloudy? Is there a whitish blob of something that appears to be floating inside of the eyeball? I've personally seen the condition in gliders that we've purchased over the years as we were building our breeding colony. I can wholeheartedly understand why someone would see this and assume it is cataracts. I've not met any doctors yet who've actually treated cataracts in sugar gliders. I think they agree that cataracts can happen, but this condition is actually related to the amount of fat in the diet.
Gliders do not digest fat well at all. It is why our own Dr C and other vets in the know recommend that the protein sources used in the glider diet be high in protein but low in fat. The goal is low in fat, not to be confused with no fat. Some fat is actually necessary in the diet, particularly with breeding sugar gliders; it is necessary for lactation.
Examples of foods that are high in fat which are not recommended are avocado, all nuts, peanut butter (unless your glider got stuck in a sticky trap!) red meat (including ground meat), pork, cheese, anything cooked in oil or butter. We use a short list of proteins in our feeding rotation here at SunCoast.
We use boiled chicken, boiled egg, mealworms, crickets, grasshoppers, yogurt and sometimes chicken baby food. During the holidays, we may also feed some occasional turkey. This is not to say these are the only proteins you should be feeding. We just feel we are able to incorporate enough variety in the diet sticking to this short and proven list of good protein foods.
And even on this list, mealworms can be a bit higher in fat than may be ideal. If you only feed them 2-3 times a week as opposed to every day, you should not expect that to be a problem as things even out over the longer term. Daily feeding of mealworms may not be the best idea for your gliders.As stated earlier, we have had a few instances of seeing gliders with the cloudy eye condition. Without having good background information on these animals, it has been hard for us to discern whether the condition can be completely cleared by changing to a correct glider diet. We have seen improvement in affected animals over time, but not a complete clearing in all cases.
And the consensus was clear amongst the team of professionals we've discussed this with. The major concern is not what permanent damage has been done to the eyes or vision, but what are the ramifications for the fat buildup in the rest of the body?
Your best bet is to stick with proteins that are lower in fat count. This will be the most supportive approach for your sugar gliders' long and happy life. And next time they wink at your with their big, black, clear eyes for another great meal served, feel good about your choices!
