We took Eli for his second follow-up appointment last night. His September appointment's test results revealed remaining grit in his urine and the pH balance wasn't acidic enough. The vet kept him on the Hill's Prescription S/D food, which we fed Eli until about two weeks ago when we ran out. I figured we'd feed him the S/D kibble and Morty's canned Wellness food until the next doctor appointment rather than buying another case of expensive prescription food that we might not need.
Eli was a good boy at the vet's, weighing in at 13 lbs. I hope he doesn't get much heavier. He did not enjoy having his temperature taken, and stuck his tongue out at the vet after she examined his gums. Thankfully, they were able to get a urine sample (vet was worried with Eli's bladder not being very full); otherwise, I would've had to wait around for Eli to pee in a specially prepared litter box and collect the sample myself and bring it to the vet.
The vet called me this morning and said that Eli's test results are "fabulous" and that we should keep feeding Eli the way we are and he doesn't need another follow-up appointment. I'll probably be a little anal though and bring him back for another urinalysis in 6 months. The price wasn't too bad either, totaling $87 for follow-up and urinalysis. Not too bad considering it's a fancy Park Slope clinic.
