Corneal Sequestrum in Cats

Corneal sequestrum in cats

What is corneal sequestrum?

Feline corneal sequestrum (FCS) is a common eye disease characterised by round or oval brown or black plaques (spots) on the cornea which are made up of necrotic (dead) corneal tissue.

Why Do Cats Flop Down In Front Of You?

Why do cats flop down in front of you?

Flopping at your feet is an effective way to elicit attention from you. We have two choices, step over the cat or respond to the cute ball of fluff at our feet. For most people, the flop is guaranteed to make a person react with attention and by responding to the cat, we are rewarding it with positive reinforcement.

The belly is one of the most vulnerable parts of the body, and cats instinctively know this. Several critical organs (kidneys, liver, pancreas) are located in the belly, therefore cats will only show their belly to people they trust, or when they are being submissive towards another cat. The submissive and vulnerable cat will have his or her ears pulled back and the limbs raised in defence. This is very different from the flop at the feet of a human companion.

Cauliflower Ear in Cats

What is cauliflower ear?

Also known as a perichondral hematoma,  cauliflower ear is an irreversible deformity caused by the formation of scar tissue and contraction of the perichondrium which occurs after a separation of the ear cartilage from the underlying connective tissue.

The pinna is the outer part of the ear that acts as a funnel to direct sound further into the ear and is made up of three layers:

  • Cartilage plate: The innermost layer of the pinna provides the shape and rigidity. Unlike other tissues, the cartilage lacks the ability to heal itself when damaged.
  • Perichondrium: A protective layer of connective tissue that provides the blood supply and nutrients to the cartilage. The underlying cartilage and the overlying skin are both firmly attached to the perichondrium.
  • Skin: The outermost layer of skin that is covered with short hairs on the outside.

As the cat scratches the ear or shakes the head (head shaking is more common in floppy-eared dogs), the perichondrium separates from the cartilage which creates a space. The perichondrium blood vessels rupture and blood pools in the pocket-forming a hematoma. This build-up of blood between the perichondrium and cartilage can interrupt the blood and oxygen supply to the cartilage causing necrosis.

The distortion of the pinna, which becomes hard and cauliflower-shaped (hence the name) is thought to be due to a combination of factors which include myofibroblastic contraction of the maturing granulation tissue, excess cartilaginous tissue (preexisting and newly formed), and the separated perichondrium retracts and acts as a bowstring, gradually folding back the cartilage.

Tomcat Jowls in Male Cats

What are tomcat jowls?

Also known as stud jowls, stud cheeks or shields, tomcat jowls are fleshy areas which develop in the cheeks of intact male cats due to the effects of the hormone testosterone.

14 Unusual Breeds of Cat

The difference between cat breeds isn’t quite as vast as that of dogs but many cat breeds have unusual features that make them unique. This may be curled ears, short legs or unusual fur. Most of the cats arose from a spontaneous mutation and were developed to create new cat breeds.

New breeds which arise from spontaneous mutations take years to develop, breeders must determine if the mutation is dominant or recessive and if it causes any long-term effects on the cat. Established breeds or domestic (mixed-breed) cats are often utilised to increase the size of the gene pool.

Dominant vs recessive genes

Cats acquire two copies of each gene, one from the mother and one from the father. A dominant gene only needs one copy for the trait to be expressed, whereas two copies of the recessive gene must be inherited to be expressed.

Some cats may inherit one dominant and one recessive gene, the dominant gene overrides the recessive, which is not expressed. However, if the cat mates with another cat who also carries the same recessive gene and the kitten receive a copy from each parent, the trait will be expressed. This is known as a carrier.

In some cases, a doubling up of a dominant gene (homozygous) is lethal.

How Did The Longhaired Cat Occur?

At a glance The coat of a longhaired cat occurred due to a mutation (alteration) of the FGF5 gene (fibroblast growth factor-5), which is thought to be an inhibitor of hair elongation. The longhair mutation is thought to have originated in Russia before migrating to other parts of the world. Longhaired cats have an advantage … Read more
