To the OP- Yes, vet care is expensive and times are tough. But if there was something you could do that could improve the quality of your pets life, wouldn't you at least want to look in to it? And if all the tests come back negative, isn't that worth knowing, too?
There is a great thread on some ways to get help with vet bills.

I hope you will be open to at least looking at that thread. And I do hope that everything works out well for Deputy.
