Wow, what happy news!!
He must be doing well for the vet to refrain from doing the blood tests and leaving the next visit until the end of May. Yeh! Did he not think it worth giving you anti nausea meds should Bentley go off his food again? If he really has kidney disease it seems to be in the very early stages and that is great news.
Hoping little Bentley continues on this good path and that you are feeling less stressed now. Please keep us posted on how he is. Thank you for the updates, we so appreciate knowing how he is doing.
