Hey so glad to hear you found a vet you feel comfortable with! That is so important!! Hang in there and hopefully you will figure out what is going on with the little guy! And if you do have to home cook for him, well let me just say it really isn't that bad at all. I was so worried about it being extra expensive and taking up a lot of my time. But really it is not so bad.
And Rosie loves it! She is doing so much better on it. Hopefully you will be able to resolve the issue without having to do much more. Good luck to you and hugs to Gizmo!
