On top of the prescription food. She may keep eating.

You could also ask the vet if there are other flavors or brands of the food she needs.

I used to mix my cat's meds with chicken baby food - maybe adding a small amount of that to the Rx food to entice her to eat more of it would work, or one of those treat things, like Churu.

My cat did not like Hill's either but the comparable Royal Canin - wet and dry worked out. I was prescribed Urinary SO cat food. They also have a low calorie version.

It is really worth getting them on that food because it does work. My cat never had another problem with crystals or stones and he lived a long time and no test showed them again.

She loves it.

Hill's is the worst food and cats know it. Mine won't go near it.

I would switch to wet food first. Google natural remedies and treatments.

catinfo.org has a lot of good information on cat nutrition. She saved my Abby's life in 2005 and he lived another 10 years after we changed his diet. He had inflammatory bowel disease and his vet recommended a Hill's prescription food that only made him worse.

spoon to a pate cat food. Gradually increase to 1/2 t once or twice a day. Cats don't drink a lot of water and adding water helps with hydration and hydration helps prevent stones. Also there's an on-line homeopathic store that sells a tincture called "Tinkle Tonic." It works and the cat can be on it all their life.

With these tinctures you'll get dosing instructions but I suggest you give just 1 drop per meal for a few meals (with water added) and increase from there to fool a finicky cat.

The man who owns the tincture store is VERY knowledgeable and a world wide speaker on animal health issues. The name of his company is Animal Essentials.

We have a cat that had crystals in his bladder.

Vet put him on a purina veterinary prescription food, dry and wet, he and his sister love it.

I give them dry 3 times a day ( auto feeder ) and 1/4 can of the wet with lots of water mixed into it to encourage water intake. It's really a wet food soup, but they knock it right off and come and beg for it every night.

Expensive food, but there has been no further issues.

We transitioned his sister to it after talking to vet, and other than cost it's fine for her.

It costs about $100 a month for the wet and dry food.

But it's worth it and having them both on it makes it much easier.

I hope you find a good solution for your kitties.

Have to agree with prior posts - 1) that most cats do not like their special foods, 2) the tinctures have helped our dog with his itching so the naturopathic methods might work, 3) putting a more favored food on top or mixed in could encourage consumption of the special diet food, and 4) give alternative brands to Hills a try.
Nnadir, I know you are a keen scientist. Asking friends about their own experiences is an important research and information gathering method! Best of luck to you and your cat!
