I went to the Lincolnshire/Humberside cat club joint show in Doncaster, and there were quite a few MCs there, including my breeder who was showing her stud cat and one of her females. MCs were quite well represented, I'd say about 15 MCs were there, just as many in fact as other breeds.
The stands were good, nearly spent £150 on a Tigga Tower! But managed to control myself and just came away with a little brush.
