What Is Catnip?

Catnip is a plant that lives more than two years, from the mint family, that is often used for tea infusions due to its calming effects on humans. They grow up to 100cm tall and 50cm wide. Its leaves may look like strawberry leaves, some claim both plants are somehow related, but this is just a myth. These plants are known to grow better under direct sunlight, and you can expect them to produce flowers from spring through fall.

Oil can be extracted from this plant by steaming its leaves; this method allows the steam to mix with the recently evaporated oil, the resulting mix is condensed, the liquid is poured into a jar and allowed to rest for about 24 hours, during this time the water and the oil molecules will separate, leaving the latter on top, now you can easily collect it and store it in a spray bottle or a smaller jar. This liquid is believed to have a repellent effect on mosquitoes, cockroaches, and many other insects.

The Effects Of Catnip On Felines

Studies have shown, one out of 3 cats is not interested in catnip at all. Experts determined most cats are attracted to this plant due to an inherited behavior from their parents. However, some broader studies performed concluded this plant has a similar effect on other feline species besides domestic cats. Testing has been done on cougars, leopards, lions, and lynxes; all of them showed pleasure and enjoyment after being in contact with the plant.

  • Rubbing its body against furniture, household members, etc.
  • Purring
  • Rolling on the floor
  • Jumping playfully

What To Expect If My Cat Eats Catnip?

Most of the aforementioned effects happen when the cat inhales catnip fumes, it is believed that when a cat breathes in catnip’s active ingredient nepetalactone; chemical reactions begin to alter its brain activity, resembling a state of euphoria.

There’s no need to worry if you find out your furry friend ate a few catnip leaves. Cats are really good at controlling their needs and won’t exceed the amount of catnip their metabolism could digest at once. In the event a cat eats too much of it, its body will respond by vomiting. If this mechanism fails, then your pet will end up with an upset stomach and eventually diarrhea.
