Too many supplements given to pregnant animals may be a major cause of the development of congenital cleft palate in cats and dogs
Cleft palate is a common congenital abnormality that is seen in cats, dogs and other species. If there is a serious defect the individual may die early due to inhalation pneumonia, and treatment may not be possible.

Too much dietary vitamin A intake during pregnancy has been shown to cause cleft palate.
Commercially prepared complete pet foods contain more than sufficient available vitamin A yet breeders and owners frequently supplement their pet's ration with vitamin supplements. High vitamin A content is also a feature of many natural food sources including liver and fish oils. Cod liver oil is a very popular nutritional supplement with pet owners and it contains 18000mg per 100ml (4000 IU per gram). Some vitamin injections contain as much as 500,000 IU of vitamin A per ml.
Provet's Recommendations :
Provet is conducting a survey into the possible link between vitamin A intake and the development of congenital cleft palate. If you have had a case and can recall the food and nutritional or vitamin/mineral supplements that your bitch was fed through pregnancy please send full details (or ask your veterinarian to send them) to firstname.lastname@example.org. Thank you.
