Hi! Sorry we have not been in touch lately - moving house at the min so had no internet for a while...
...anyway, to cut a long story short, Dusty still had red urine by the end of her course of Noroclav so I booked her in to see the original vet who was back off his hols and he was disappointed that the other vet had prescribed Dusty Noroclav as it's apparently not an antibiotic he would choose to give to rats as it's a penicillin and quite harsh (good job I didn't mention the OTT course of painkiller the other vet had prescribed at the start of the course

) I took another urine sample which he tested and found blood present and he basically said it is either a UTI that will clear up with Trimacare (the antibiotic you had suggested she should be on) or he explained about a degenerative illness to do with the kidneys as he had found a high level of protein in the urine sample, he said there might be cysts that build up causing the bleeding... not sure what to think of that especially when he mentioned that you can't cure it only control the illness - poor Dusty. Anyway, looking on the bright side he prescribed two week course of Trimacare (in tablet form, even though the other vet told me they were too hard to crush

) and Dusty is doing great on them, her urine is not red and seems back to normal, so fingers crossed this works.
I did mention urine crystals to the vet and he believes that these are not very common in rats as it is usually bladder stones, so he said we could opt for an xray if Dusty still doesn't improve after this course of antibiotics.
It does look like I'll be going to the vets again very soon, as one of my other girls 'Chase' in the same cage seems to be having difficulty opening one of her eyes - I think she might have got into a fight and possibly been scratched in the eye as she is lively as usual and doesn't have any other health problems... these vet visits are becoming far too frequent.
Any advice would be welcome!
Thank you!
