my Briosa has early kidney disease. very picky but she does eat canned Purina (from vet) NF for kidney disease. at first they had me add a little of same brand but added a little of AD kind for flavor. might try that. and for the running water, try petco or foster and smith animal stuff for a fountain type drinker. many types, many prices but much cheaper than having your water run! they like the moving water and usually drink more. good luck.
