I am so sorry to hear he is going thru this again. I watch Gizmo like a hawk when he goes outside to do his business just in case there's blood in it again. We went thru a bad attack over a year ago and has had a couple small ones. I really don't think there's anything else I can do. The condition is there and I just have to deal and give him his Reglan when is needed and hope it doesn't go full blown. Poor baby, I really hope your little one is feeling better soon, it is helpless to watch. You just need to know when to get to the vet in time before the dehydration set in. Biggeriest hugs to Zues, and to Mommy too.
