"If you'd meet Val you would never forget her, she was extremely outgoing and a real character.
"We've invited people, judges, who had a lot of respect for the two who have gone, and who Margaret and Val in return had a lot of respect for.
"As soon as I started talking to people and mentioned Margaret and Val they all said yes straight away."
With 120 cats registered for the show, the show proposes to be a successful one with cats such as Graham being judged on confirmation, compared to a written standard.
"They don't actually compare a cat to another but to a written standard. With a Persian for example, everything about a Persian has to be round.
"Round eyes, a round head, round ears and a round body whereas a Birman is a different style.
"It's still a long haired cat but its more medium in length with a longer tale, a nice little roman nose, point colouring of course and you want those four feet to be nice and even."
Lyall has been a judge in the past but is too busy organising this year's show to be involved in judging.
With judges from New Zealand and Australia and cats and their owners from all around New Zealand the show will be a tribute to two larger than life characters who were so important and influential in the hobby of showing and breeding cats.
