I got great news from the Vet today. There were some concerns that Sly had stomach cancer and even though it is unusual for his age it was a relief to know that wasn't the case. We are adding another medication to his treatment plan (for a total of 5 now), but am very happy that we are hopefully on the road to recovery.
I am hoping that the Meds will kick in quickly and we will have an enjoyable trip to Idaho!
Thanks for all your prayers and support through all of this.
