The document discusses the Munchkin cat breed, which is known for having very short legs due to a naturally occurring genetic mutation. While early concerns existed that the short legs may cause spinal problems, studies of the breed in the 1940s and 1950s did not find this to be true. The short-legged trait is caused by an autosomal dominant gene, meaning there is a 50% chance offspring from Munchkin parents will also have short legs.

4. information
• They have very short legs, which is
caused by
a naturally occurring genetic
mutation.
Early speculations that the
Munchkin will develop spinal
problems commonly seen in short-
legged dog breeds did not materialize .

5. History

6. information
• A British veterinary report in 1944
noted four generations of healthy
short-legged cats which were similar
to normal cats except for the length of
the legs.
This line disappeared during the
Second World War but other short-
legged cats were spotted in Russia
during 1956 and the United States

7. Genetics

8. information
• The munchkin gene is an autosomal
dominant one .
For each kitten born from this mating, there
is a 25% chance it will not survive, a 25%
chance it will be normal, and a 50% chance it
will be short-legged.
