also the receptionist said taper her into eating this at 10/90 at first and graduate for four weeks or so to transition from old food. do you recommend the same? or just switch to the urinary stuff. can you send me the links for the science diet foods and do i have to keep buttercup separate while eating the s/d and when do i need to get her urine checked again and when can i switch to the UR? the vet did not say (bad vets here) and also the receptionist said i have to feed her this forever and only buy it at the vet (i see i can get it online elsewhere so she can stuff it) as it was 17 euro for the dry and 17 euro for the wet.
