Infected cats may appear normal for years. However, infection eventually leads to a state of immune deficiency that hinders the cat's ability to protect itself against other infections.
FeLV:
Feline leukemia virus adversely affects the cat's body in many ways. It is the most common cause of cancer in cats, it may cause various blood disorders, and it may lead to a state of immune deficiency that hinders the cat's ability to protect itself against other infections.
Cats persistently infected with FeLV serve
as sources of infection. Virus is shed in very high quantities in saliva and
nasal secretions, but also in urine, feces, and milk from infected cats.
Cat-to-cat transfer of virus may occur from a bite wound, during mutual
grooming, and (though rarely) through the shared use of litter boxes and
feeding dishes. Transmission can also take place from an infected mother cat to
her kittens, either before they are born or while they are nursing.
Hypertrophic
cardiomyopathy is a condition characterized by the
inward thickening of the heart muscle resulting in reduction of
chamber volume, thereby reducing the volume of blood the heart can pump
with each contraction. All Devon Rex cats should be scanned before
breeding.
Blood group:
The A and B blood groups are genetically
determined.
Blood type A
is dominant to B. Genetically, cats with type A can be A/A, A/ab or A/b and cats
with type B are always b/b.
Blood type A is the most common among cats but the frequency varies significantly by breed and geographic location.

Blood group incompatibility (BGI) can present a problem to breeders. One
of the causes of Fading Kitten Syndrome is "neonatal
isoerythrolysis". This means the kittens have a different blood type from
their mother and the antibodies in her milk attack those kittens' red blood
cells. The symptoms are jaundice, brown urine and rapid deterioration and
death. In less severe cases, the affected kitten's tail-tip drops off. The
diagnosis is confirmed by blood-typing the mother and affected kittens.
