My cat has had her blood tests and kidneys and cholesterol are normal with slightly high throid but nothing major. Her BP was high which has caused the retina of her eye to detach - but the underlying problem is her heart that had a rate of about 190-200 bpm, so she has heart problems.
So the new vet had given her a tablet to control her blood pressure and gave her a different steriod to encourage her to eat and drink as she was slightly de-hydrated. We have the daily tablet to give her each day for a week and then well be going back to check how she's getting on.

She's been back at home for about 7 hours now and she's been eating dry food on about 4 separate occasions and taken water nearly every time! So hopefully she'll begin to be a little more active soon, but already she's had much more food and water that the last few days altogether. Fingers crossed.
