London - Cats with higher levels of vitamin D are more likely to survive a serious illness, a study has shown.
Researchers from the University of Edinburgh examined blood samples from 99 pet cats that were admitted to animal hospital with life-threatening conditions.
They found that cats with higher levels of vitamin D in their blood were more likely to be alive 30 days after admission than those with the lowest levels.
The so-called “sunshine vitamin” is known to help prevent a range of health problems in humans – including multiple sclerosis as well as some cancers and infections.
The vitamin can be found in oily fish, cheese and egg yolks – and is available to buy in health food stores as a supplement.
Humans are also able produce vitamin D in their skin after exposure to sunshine, but cats can only obtain it from their food.
The team said their study, published in the journal PLOS ONE, could help inform trials of vitamin D supplements in people.
The findings may also help vets give owners better advice about their pets’ prognosis, according to the team at the University’s Royal School of Veterinary Studies.
But lead researcher Dr Richard Mellanby stressed: “It is very important to remember that too much vitamin D can be poisonous to cats.
“Most cat foods contain a standard amount and there is no need for owners to add supplements.”
