I'm so sorry to learn about Groucho. The poor baby; that's so worrying when you know that something is off but you don't know just what.. or what to do about it. I'm glad your vet is checking all this out thoroughly. Between you and her and Groucho, you will do the right things.

God bless you all. Prayers and good wishes and healing energies and white light are being sent from us.

Love from us all ,
Pat and cats
