So sorry to read about Lucy,
No matter how prepared you are,it still comes as a bit of a shock.
It's good news that she's responding well to the medication.It's important to be able to see her scan,so you can visualise the situation and I'm a bit surprised you weren't shown this at your follow up appointment.I know she means the world you and she's been so lucky to find her home with you.
Give her a little hug from me,she's had a tough few weeks and must be fed up of vets.
Sharing my sofa with Holly, Ivy,Lilly and Hazy.. and never forgetting our beautiful Daisy who reached the bridge too soon.
