I really don't know what it could be as I don't have any experience with that kinda thing. Maybe Jan or Jen can help though. They both seem to know almost everything. I really really hope Ron is ok. And I don't think he is too old to adopt out. Elderly cats make the best pets. And I can bet there are lots of people out there that know this and would take him. Let's deal with the health issues first though. Fingers, toes, whiskers and paws crossed for Ron.

Get Well little buddy we are pulling for you.
