Thank you for your reply.
I've bought some of the Readigrass Friendly packs for small animals. My Sulky is eating it although not cleaning his bowl as usual
I'm still mixing a few leaves etc. in and giving access to water.
It does seem quite sharp but I assume this isn't a problem?
Thanks for the link, I'll take a look but appreciate this isn't a complete solution. if he eats the readigrass that'll be ideal
