Thinking that you have a Down Syndrome cat can be stressful, knowing what the condition means for humans. But is it possible to have a cat with Down Syndrome? How do we account for cat Down Syndrome symptoms? Would a Down’s Syndrome cat have the same difficulties as humans with the same condition? What’s the truth behind the trend of people saying they have Down Syndrome animals?
Can Animals Have Down’s Syndrome?
The truth is, animals can’t have Down’s Syndrome, unlike humans. Down’s Syndrome or trisomy-21 is a genetic malformation that is particular to humans only.
Animals can’t get it because their genetic makeup is wildly different from humans. Take gorillas, for example, that share about 98% of our DNA. The 2% difference makes gorillas different from humans, and the differences are massive if you compare humans with gorillas.
So why are people saying that their pets have Down’s Syndrome? It’s all about the Internet and how people share information without first verifying the information. Much of the Internet contains information that isn’t information, to begin with.
To be fair to people who have pets that look or behave differently because of physiological defects, there are chromosomal defects that can affect animals’ behavior and physical appearance.
However, it is inaccurate to state that these animals have Down’s Syndrome. These defects have names and if your cat seems to look like it has some effects, visit your vet for an accurate work-up. Your vet will inform you how to care for your pet better, given its condition.
If you are interested in some factual genetic disorders that affect felines, here’s a list:
- Polycystic Kidney Disease – This condition mainly affects the Himalayan and Persian breeds of cats. When a cat has this genetic condition, they can die of kidney failure. Some of them who are more mildly afflicted may only develop cysts that can affect kidney function. A swab test (cheek swab) can help confirm the presence of this genetic abnormality.
- Hypertrophic Cardiomyopathy – This disease, unfortunately, affects the sweet Ragdoll breed and the giant Maine Coon. Cats with hypertrophic cardiomyopathy can progressively become weaker and eventually expire from heart problems. This defect occurs in up to 30% of Maine Coons. Maine Coons is also prone to developing spinal muscle atrophy and hip dysplasia.
- Lethal Craniofacial Defect – LCD is seen more frequently in the Bernese breed of cats. Scientific studies show that this defect results from selective breeding of the Bernese cat breed that highlights a wider face.
- Polydactyly – Polydactyly is a dominant trait that causes the formation of other toes. Kittens with polydactyly will often have parents that have the same malformation.
- Blue eyes and deaf – Some cats born with blue eyes are also completely deaf. This defect is linked with the W gene (white gene). Other cat breeds get their blue eyes from the C gene and, as a result, are not deaf.
What Causes Down Syndrome in Cats?
Cats cannot have Down Syndrome because they don’t have chromosome 21, the affected chromosome in humans. There has been an increased awareness of cats with special needs in recent years.
Cats with genetic malformations can have mild to severe disabilities. How these defects emerge depends on many circumstances? Some cats have chromosomal defects because their parents have chromosomal defects. Some cats infected with pathogens like the panleukopenia virus while still in the uterus can be born with signs that are similar to Down’s Syndrome in humans. Cerebellar hypoplasia also tends to produce behavioral issues that are similar to Down Syndrome.
Yet another potential cause of Down Syndrome-like traits or characteristics is exposure to toxins. Pregnant cats with the misfortune of being exposed to toxins during the gestation period can produce litters with defects. Many toxins can cause neurological abnormalities in unborn kittens, much like what happens to human fetuses when their mothers are exposed to sources of toxins like alcohol and tobacco.
Remember that once a kitten is born with physical or neurological defects, these defects cannot be reversed and will last a lifetime. All abnormalities present from birth cannot be cured or corrected, for the most part. Physical abnormalities may be remedied in some situations with surgery.
To obtain an accurate diagnosis, a veterinarian will perform the following on your cat:
- X-ray to diagnose any inborn malformations or physical defects
- Genetic tests
- Special tests to determine unusual conditions
Cats that are candidates for surgical corrections of inborn malformations may need special accessories to allow them to function properly after diagnosis and treatment. Loosely, some conditions are called ‘feline Down Syndrome’ but only because of the similarity in the symptoms.
Ensure that any pet with inborn deformations is cared for properly based on the disabilities they have. This includes taking good care of the pets by providing the right diet, accessories, supplementations, etc. The owner must also be aware of what is exactly has afflicted his pet.
Is Down Syndrome in Cats Common?
Down Syndrome cannot affect cats and dogs. However, some cats can exhibit chromosomal defects that can then translate to physical and behavioral defects. Below are some signs that are usually attributed to “Down syndrome in cats.”
- Missing nose bridge that flattens the face of the cat
- Flat nose
- Upturned nose
- Lower muscle tone and impaired development of muscles
- Cardiovascular issues
- Motor problems
- The eyes are wider apart than usual.
- Vision problems and complete blindness
- Oddly shaped ears
- Smaller ears
- Strange or awkward behavior not observable in normal cats.
What Animals Can Have Down Syndrome?
Only humans can be born with Down Syndrome. Different animals can have chromosomal defects that can affect how they look and behave. However, it is improper/inaccurate to say that they have Down Syndrome. Again, only humans have the 21st chromosome. Animals have fewer chromosomes in their DNA.
