Persians are predisposed. Normally, the testicles are in the scrotum by the age of six to eight weeks. Male cats with one cryptorchid testicle may still be fertile; however, male cats with two cryptorchid testicles are most likely to be sterile. Urine spraying is one indication that a cat with no observable testicles may not be neutered; other signs are the presence of enlarged jowls, thickened facial and neck skin, and spines on the penis (which usually regress within six weeks after castration). Most cryptorchid cats present with an inguinal testicle. Testicular tumors and testicular torsion are rare in cryptorchid cats, but castration is usually performed due to unwanted behavior such as urine spraying. Horses
In horses, cryptorchidism is sufficiently common that affected males (ridglings) are routinely gelded. Rarely, cryptorchidism is due to the presence of a congenital testicular tumor such as a teratoma, which has a tendency to grow large. References

Xerotic eczema  is a form of eczema that is characterized by changes that occur when skin becomes abnormally dry, red, itchy, and cracked. It tends to occur more often during the winter and in dry conditions. Xerotic eczema is common in elderly people, though it is not uncommon for people in their 20s. It can appear in red, bumpy, pimple-like irritations. Treatment
The first method that should be taken when treating xerotic eczema is attempting to re-hydrate the dry skin using a humidifier and bathing/showering less frequently. Mild and moisturizing soaps should be used to prevent further irritation. Scratching the affected area should be avoided. Applying moisturizing lotion or anti-itch ointment frequently should help in reducing dryness. If the re-hydration process does not alleviate the symptoms, moisturizers such as Lac-Hydrin 5% or 12% moisturizer containing urea can be used; furthermore, if the skin becomes inflamed or cracked, mid- to high-potency corticosteroids can be used.A study published in 2005 found positive results from soaking the affected area in water for twenty minutes and then applying mid- to high-strength corticosteroid ointment.
