Prescription cat food, my cat says YUCK!!!

I had posted in another thread about my cat Dagny having a UTI and crystals in his urine. I took him to the vet yesterday morning.  He is on antibiotics (pill) and some gel for him to eat that is suppose to help with the crystals (it is horrible smelling and I have to put in on my finger and put it in his mouth).  But at least these 2 things are possible to do.  BUT the prescription dry cat food (they were out of the moist) is something that smells horribly putrid and he refuses to eat this at all and he is always a hungry cat.  It is the Hill's prescription brand.  I know that going without food for any extended time is not good for his liver either so I'm very concerned.  I even mixed a little bit of his regular moist food in with the prescription food a little while ago to see it it would tempt him.  He ate around the prescription food picking out the regular moist and I would hear an occasional crunch from  a piece of dry prescription food that I'm sure he ate by accident.  He did not eat much at all, but at least he ate something.

I'm going to call the vet tomorrow and  tell him he will not eat this horrible stuff and I think he will starve to death before he will eat it.  The saying, "If he gets hungry enough he will eat it" is simply not happening with him and I feel so sorry for him I can't stand it.  I love this cat with all my heart and I want to do what is best for him, but he will not eat this stuff.  He looked at me as if to say, "what did you do, get my cat poo out of the litter box and put it in my food bowl?"

Does anyone have any suggestions until I can contact the vet tomorrow?

I would get one of the high protein, low carb wet foods for now just so he has food.  I don't know what you are feeding now but any food is certainly better than nothing.  Cats are fully capable of starving themselves to the point of serious illness.  The old adage they will eat when they are hungry enough does not hold true for cats.  http://www.catinfo.org/docs/FoodChartPublic9-22-12.pdf  is a chart that shows the protein/fat/carb percentages for most commercial foods available in the U.S.

Is this bad tasting dry food a good provides a good mid-range ph of urine, or one that is supposed to dissolve struvite crystals (if the latter, hopefully your cat's crystals were tested as in fact many cats have oxalate crystals and a food for struvite crystals will make things worse in this case)??

My cats don't mind some of the dry Royal Canin foods that are designated as S/O balanced. So designed to stop both types of crystals from forming (but won't dissolved existing stones etc.) They have one called S/O but some others are also designated as S/O balanced (they indicate this on the packaging with an S/O designation). My cats like the Adult one ok, and the GI one seems to be ok tasting.

Also, for urinary-challenged cats, generally wet food is thought to be best as it adds the necessary moisture into their body that helps prevent crystal formation. So if the cat won't eat the special prescription foods or the ones I mentioned above, getting wet food into them is a good thing.

My cats are on as much wet food as I can get into them supplemented with the Royal Canin Adult dry food (I've tried to change them to an all-wet diet but my senior cats have multiple issues and keeping weight on them is important so I put out some dry as well).

I have a couple of cats with urinary issues, and there is no way that I can get them to eat the wet prescription foods - they would sooner starve than eat them and in the end, more damage can be done if they are not eating, so my cats are on other wet food.
