Hi Ann....I have been thinking about Tina and just logged on to see that you had taken her to the vet for her assessment. It is sad to know that she is getting older and has developed some age-related problems. However, it is always better to know what we are dealing with and I am sure that the vet will help you as much as possible to keep Tina healthy and happy for the rest of her life. Taking her outside more often is a good idea and should make the sitaution easier to deal with. Give her a hug from all of us here at Pet Talk and take care....regards from Deborah in Montreal, Canada
