my cat is very sick, it wont eat and wont drink. we took her to the vet, and she got an inj. of polyflex , clavamox drops and we got 3 cans of hills prescription diet cat food. we add a little water to the food and we give it to her in a squeeze bottle. she is very weak and just sleeps. my wife took her into the vets yesterday. i have stayed up all night with her, i have wiped her eyes and nose, kept her warm, and held her up in the kitty litter box last night, she did pee. the vet said it may be her kidneys .... please help...
