She didn't seem to really drink much water when she came, but as she was eating wet food only, I didn't think much of it. This weekend, I have noticed her at the water bowl quite a lot. I haven't just changed her to a more dry food diet (although I have just found some more biscuits she will eat), although some of the drinking did start just after she had finished eating some biscuits. Looks like I won't be able to put off the blood test till the end of the month, better see how quickly work can let me have some time off!! I don't think it is anything too major, but it is niggling at me, so I will only drive myself daft if I don't get it checked!! She does occasionally hold her left paw up to her chest, as though it needs resting, so will be getting that checked out too.
