I joined up my sister in law to the mykitten group and she only got a free coupon for food too.
My parents surprised me in late august with a kitten so I joined the site and I believe it asked if I used litter and what kind and I said yes and their brand.. It could be a new deal perhaps.

i joined mykitten.ca not to long ago and i had only got an FPC for kitten food. oh well i guess..lol would of been nice to get free litter..i have 2 cats that love to make messes with their litter. lol

I got the Purina Free pail of litter and bag of kitten chow by joining mykitten.ca =)
