Josh Caddy says the Cats aren't fazed by the wet weather predicted for Friday.

The Bureau of Meterology is predicting between 10mm and 30mm of rain to fall in Melbourne, although the worst of the weather is expected to pass by the time Geelong and Hawthorn run out to contest their qualifying final.

"Finals footy is that contested brand of footy anyway, so we've already got our heads wrapped around that," Caddy said on RSN's breakfast show on Wednesday. 

"If it's a little bit wet, then that will be fine.

"It might suit me a little bit better actually, so it's fine."
