Some species of mongoose can be easily domesticated, are fairly intelligent, and can be taught simple tricks, so they are often kept as pets to protect the home from vermin. However, they can be more destructive than desired; when imported into the West Indies for the purpose of killing rats and snakes, they destroyed most of the small, ground-based fauna.
For this reason, it is illegal to import most species of mongooses into the United States, Australia and other countries.
Mongooses were introduced to Hawaii in 1883, and have had a significant impact on native species. Mongooses are sometimes referred to as "the most dangerous animals on the planet" for this reason. Wikipedia
In India they're listed as a protected animal under the Wildlife Protection Act.
I recently ordered half a dozen mongoose brushes, Isabey series, which I've used before and liked. At the time the handle said Isabey-France. This time, no France, but "Memory". They didn't look right or handle well, and the black tips pretty much came off in the wash. Only one art supplier refers to them as "Mongoose-like", others as Mongoose. So beware.
I don't like to think that an animal has to be killed for my paintbrushes. Or my hamburger, for that matter.
The best bristle brushes as everyone knows, are hog bristle. Or as one source delicately put it, male pig. If porkers were butchered only for paintbrushes, they would probably be on our Wildlife Protection Act.
And what of the badger blender? The sable? Better a brush than a coat?
