catamount

There was no time to retreat, for he heard, close by, an angry snarl from the catamount.

The strange, upright pupils of the catamount's eyes narrowed and dilated at the sight, and his muscles quivered to sudden tension.

A catamount would tear you to bits with his great claws before you could run!

Our native hunters never heard the word lynx, but call the animal a “catamount.”
