Siamese cats are very vindictive and aggressive. Many owners get new scratches and bites every day. If a Siamese cat has held a grudge against you, you should wait for revenge.

Mekong Bobtail is a very old breed. They look like kind cats. But in reality, it`s not true, because Siamese cats are their ancestors.
Mekong Bobtails don`t have a sweet personality. They are dangerous and independent.
