Bad news everyone.
Mertyl was taken to the vets on Saturday to try and cure her squirts and vomiting.
Mertyl seems fine but apparently she has two of the three symptoms (sick/pooing plus high heart rate) of an infected thyroid gland. She's on this special medicine and has to get a check up in a few weeks.
I think there is an operation that they can do but it's quite expensive and seeing as she's quite old they think that it's not worth while. We'll see.
Poor little stinky rat face.
