its going to be difficult if they don't have the money for more investigations but uti is likely. If the treatment improves things sounds like vet is on the right track
They could ask for a urine sample to be tested as maybe more target antibiotics are needed than a broad spectrum one. Have anal glands been checked ?
. However the vet maybe aware of the financial circumstances and doesn't want to push for too many investigations
Regarding low income are they eligible for pdsa care ?. It wont change things very much but may help their finances . .
Is the wriggling connected to pain and so reduces when the painkillers are given or is it just a habit. Mine wriggles on her back frequently but its because she just loves the feel especially on our artificial grass not because she has problems
