Hi Everyone, I thought I made a post letting everyone know that I was finally successful with the ketone testing, but again not sure what happened to it! Still having trouble figuring everything out here, even though Deb has given me so much help! Anyway, I am posting again because I wanted to make sure everyone knew that Charms tested negative! I used all of your advice, locked him in a room, me, Charms and the litter box. When he finally decided to go I just put the strip under him like you suggested and it worked. Thank You , could not have done it with out all your help.
