Vet pulls bug from kitten's nose with tweezers

There has to be a warning about this video which you can also see on Twitter. It's a short video of a warble (the lava of a botfly) being extracted from the nose of a young kitten. It looks gruesome and it is pretty gruesome. You don't want to watch it if you've not got a strong stomach.

It is a curiosity because it's quite rare but in the US and Canada (also in Mexico and the neo-tropical regions) there is a species of fly, Cuterebra, which lays eggs near or in the opening of rodent and rabbit burrows. These eggs develop into larvae and the larvae can burrow into the skin of cats, kittens and dogs. They might enter the cat through the nose, mouth or a skin wound.

The lava develops in the skin as part of their life-cycle. It's at this stage that a lava has been pulled out of this kitten's nose in the most gruesome video on this page. If the lava is left to develop inside the cat the botfly larvae migrate to the tissues beneath the skin where they encyst to continue their development.

Some species of botfly larva migrate to different parts of the body. Once they have developed inside the cyst, which may take from 19 to 38 days inside small rodents and from 55 to 60 days in Jackrabbits, they leave the host and the lava develops into a pupa in soil or plant litter on the forest floor according to VCA hospitals. The cyst left behind can cause an infection and be more of a health problem than the parastic larva.

If a botfly is developing inside a kitten's nose as we see in the video then it is a misfortune that the kitten has become a host for a fly. Botfly larvae are called warbles. They look, as mentioned, horrible and the thought of them is horrible but they are a fact of life.
