Understanding a cat's sense of smell

Cats have a powerful sense of smell. In fact, it is estimated that their sense of smell is 34 times stronger than ours. They also have a layer of tissue in their nose that is specially adapted for trapping scent molecules.

This heightened sense of smell is because cats have more scent receptors in their nose than we do. Humans have six million scent receptors in their nasal passage compared to a cat with 200 million.

This allows cats to pick up on even the slightest of smells. For example, a cat can smell something that is diluted in water.

Cats use their sense of smell for a variety of purposes. They use it to communicate with other cats, find food, and navigate their surroundings.

A cat’s sense of smell is also thought to play a role in their memories and emotions. Certain scents can trigger happy memories or make a cat feel comfortable and safe.

On the other hand, certain smells can be very upsetting to a cat. This is why it’s essential to be mindful of the products you use around your home and avoid using anything with a strong scent.

Cats versus Dogs: Sense of smell

Cats have as good a sense of smell as most dogs, with the exception of bloodhounds and other scent hounds. These dogs have as many as 600 million scent receptors in their nose and have a very powerful sense of smell.

Most breeds of dogs have a lot fewer receptors, and their sense of smell is comparable to a cat or lower.

Scientists have concluded that cats have a more extraordinary ability than dogs to distinguish between different smells, so they are more likely to be affected by strong odors.

The V1R receptor determines how well humans and animals can differentiate between smells. Felines have a V1R receptor score of about thirty compared to just nine for most dog breeds and two for humans

Dirty litter box

Cats are generally clean animals and hate the smell of a dirty litter box. In fact, many cats will refuse to use their litter box if it hasn’t been cleaned for a while. This can cause hygiene issues in your home as the cat may find somewhere else to go to the toilet, such as in your plant pot.

Essential oils

Some people will recommend using essential oils to stop cats from scratching your furniture or keep them away from other areas in your home. You’ll need to be aware that some essential oils are toxic to cats when doing so.

It’s best to be cautious and never use essential oils if your cat is likely to be able to have direct access to the area that’s been marked with the scent. Certain oils, such as tea tree, can cause a cat’s internal organs to fail.

If you have a cat as a pet, avoid using defuses that use essential oils and consult your vet as soon as possible if your cat has come into contact with oils.
