I'm so sorry about Ripley...I feel for you so much, because we just went through this with our Billy last year...I am hoping and praying so hard for you guys and for your Ripley...I've lit another candle for him at Light a Candle in the PURR group...Have you asked the vet about taking something like Pepcid or as Medusa suggested, aluminum hydroxide gel?...Both can help the stomach acidity which is behind the ulcer problem. I hope that they are able to help him, bless his sweet old heart...

God bless and hang in there...Hugs and prayers to you both
