Hello girls,
good news, we went to another doctor for Kelly and she said that she has to take away only a little piece of the paw but bones are ok, and even if that may be cancer, she only see the lungs of 12-years-old cat and nothing about tumor. She could be ok as well after the operation dor years. I'm so relieved! Mum will take her at clinic in the afternoon for the paw operation. I'll keep you informed. Many thanks for your thoughts, they made my day.
Apest and Kelly
