A relatively new streamer pattern developed in the 80s by David Train, funny enough he used his cats whiskers to tie the fly hence the name.
This is rated as one of the most popular streamers in the UK stillwaters today.
This fly rides hook point up so no worries about snagging on the bottom.
Fish on a sinking line with a long leader and fish slow.
The orange body works extremely well during the spawning season.
