oh dear... still saying prayers for the poor girl... hope you find some answers when you take her in, and I hope her appetite comes back. Any possibility of doing a partial blood test just kidney liver and such? Its cheaper, may give you bit more of an idea of any problem area... someone also mentioned valium as an appetite stimulant. Now of course it depends on what is exactly going on with Benni, liver, kidney, tooth infection etc. but it does work amazingly given on a short term basis. Had a kitty with a bad infection stopped eating all together gave her antibiotics, only clavamox though still didnt eat, then gave her some valium for a few days and it worked wonders.
that things get better here, and that the other fur kids are feeling better in the house too..
