Update: hi all, thanks for all your advice. Both are feeling better, only thing is that their voices aren’t back… one has a very raspy voice and the other well he must realize he has no voice and doesn’t try to use it.
mom conflicted in taking them to the vet bcs I don’t feel they have given me a proper diagnosis….finances are very tight right now…, don’t know what to do
