Just a quick update - FiFi is now fine- teeth out , abcess is healed up , just waiting for fur to grow back on her cheek.
She is eating well and back to normal now thank goodness.
She loved a tiny drink of milk -so, i emptied one of the antirobe in it whilst she was asleep upstairs -i took it up to her and she would not drink it !
I am sure she knew there was something in it even though she was upstairs and i did this in the kitchen downstairs !!
She hasn''t bothered with milk since and i gave her the rest of the tablets the normal way.
