Thank you for replying.
Holly has been eating and ate the majority of her dinner yesterday
so i'm hoping she will eat today but I think a trip back to the vet may be a good idea. she has been drinking but not excessively. The vet did check her teeth and gums and both ok and listened to her heart which she has a slight murmur and she did mention about blood tests if the urine was ok.Holly does not urinate any more than usual.
