Bagpuss and I both have the same problem at the moment. Namely Cystitis!
With Baggpuss it is an ongoing complaint and with me every 3rd or 4th attack is a bad one so Friday saw the Doc at the vets picking up a repeat perscription and me at the doctors getting a course of stronger pills .
When I was dispensing them back home I saw a potential hazzard. Spot the difference.
I don't think I will let the Doc dish any out just in case he is colour blind.
