Hi, does giving cats wet food ( gravy food) make their urine diluted? Few months ago I had started giving my cats some dry food as they are fussy eaters with wet food but like dry food. One ofmy male cats started to drink water especially after i fed him Perfect Fit dry food. One day he had drank the full bowl of water. I stopped the food straight away. I had one brand of good quality dry which i started to give my cats. This food has phylu phylum husk, brewers yeast, FSO prebiotic added. This also has d mannose mannose added to dilute the urine.. It has herbs added especially one herb added like lavorage whichvalso dilutes the urine. I stopped this food as one of my cat started to vomit white foamy liquid early in the morning. I stopped all dry and only wet in gravy I'm.feeding now. But my same cat was still drinking some water especially after having breakfast. So i took him to the vet and they tried to take his bloods but he was hissing at them. I tried to take his urine sample at home but having multiple cats made this really difficult. Especially as he doesnot like using clear non absorbent beads in his litter tray. Few days ago i thought i have managed to get his urine but afterwards my mother told me that while I had gone out of the roon to open the front door, another cat had entered into the room where the clear bead tray was. So I'm not so sure now if its his urine which i have given for testing to the vets. Anyway today the vet rang to let me know about the result and she said every thing was normal no blood, no sugar, no protein but the urine. Was diluted. My one cat who died in July 2024 had diluted urine and was drinking water. After blood test we found out she has fourth stage kidney failure. So I'm worried now. He appears normal and is not drinking daily as before. My question is that is this possible that eating gravy rich foods and drinking water has diluted his urine? I will have a blood test for him soon. But surly if there was any kidney disease protein would have been found in his urine sample. Plus he's not drinking as much as before. D mannose in his food also might have diluted his urine. Plus lovarge herb. Thank you so much for reading my long post. Roughly how much water| liquid in diet can dilute a cats urine?

Hi. I am by no means an expert, but I think there is no possible way for a cat to drink enough to over dilute their urine. Diluted urine, as it seems you know, is often an indicator of kidney disease. The best way to confirm that is to see if anything in the blood work (chemistry panel) shows an elevated creatinine (and maybe BUN) too. The SDMA test, often run concurrently with blood work, is believed to be an indicator of the likelihood of kidney disease developing. I think that is probably true for most cats, but Feeby's SDMA was never in the range to indicate so.

I had her on pure D-Mannose and it never affected the dilution of her urine (she did have kidney disease and had dilute urine long before her blood work numbers indicated such). I've never read anything about it diluting urine.

While people do say that d-mannose helps with overall bladder health, the primary thing it does is help flush out certain types of bacteria from the bladder in order to reduce any accumulation that could lead to inflammation and/or infection. Bacteria adhere to the d-mannose molecules and are excreted out with the urine.

Generally speaking, the more water a cat drinks, the better.

Yes, dry food and other foods that have fiber and things will make a cat more thirsty and they will drink less when eating only wet food. As to how much dry food and fiber will cause a cat to drink more is an open question. It depends on how much dry food the cat eats. Ideally, a cat should eat wet or canned foods but that's not always possible. Many cats eat a mixture of wet and dry foods. Our cats do. As long as they are getting at least 50% wet food, they should be okay but, as a rule, the more wet food the better.

How much water or moisture in a cat's diet will cause urine to dilute? Almost any water will but, as to limits, it depends on the cat. Assuming that the cat doesn't have any kidney or liver problems, more dilute urine is probably better because it helps wash away any "bad stuff" from the cat's urinary tract and prevents crystals.

How do you gauge the amount of water a cat drinks and decide how diluted its urine should be? Watch the cat. A cat should pee at least once or twice a day. Maybe a little more. Maybe a little less. Three or four times a day isn't out of the question but, if less than a couple of times per day, that's not good. If the cat seems to need to pee all of the time, that's bad, too. It's a balancing act, really.

Another thing to notice is how much the cat's urine smells. Cat urine can smell pretty strong but, when diluted, it will smell hardly at all. If you can smell a cat's urine shortly after he pees but the smell fades shortly afterward, that's probably okay. He's probably getting enough water. If it smells up the whole house, the cat probably needs more water.

If you are worried because you have had one cat that died and your concern is that your current cat might be going down the same road, that's another thing to talk to the vet about. Simply tell the vet, "I had one cat that died and I don't want the same thing to happen to this cat." Tell it like it is. Right? If you don't feel like your vet is telling YOU like it is, that's another sign that you should look for a new vet. (I'm super big on having good communication with our vets and it bugs me when vets don't give their clients the information they need.)

The only suggestions I can make would be to cut out some of the fiber. (psillium) Cats don't, generally, need to have that much fiber in their diets unless they need it for some reason. Giving it on occasion might be okay but I don't think it's necessary as a daily supplement. If your cat has a reason to need it, okay, but not for an already healthy cat. The same goes for the probiotic supplements. Sometimes, yes, but not every day. This is probably a question best answered by your vet. That's what they go to school for! Isn't it? ;)

By what I'm reading from you, it sounds like things are mostly okay with your cat(s). If your vet says that your cat in question has a clean bill of health, I'd trust them. (Unless you don't trust your vet, in which case, it's probably time to find another vet.) IMO, keep doing what you have been doing and I think your cats will be all right. If you think there's a problem, ask your vet.

The vet has said to give 12 ml in the night before and 12 ml in the morning before the visit. Is this too much dose for 4.5 kg cat? He might have lost some weight as being fussy with food

What med? Doesn't the bottle state the mg potency of the med? There are many different potencies available. If this is gabapentin we are talking about, the typical starting dose is usually 50mg. When in ml, I think the most common is 50mg per ml, and if so 12ml sounds like a lot. So, you need to find out the mg potency. The liquid form of this med needs to be refrigerated.

Finding the right dose for any cat is somewhat of an experiment, some cats need more than others. When using it the first time, following the vet's instructions is about your only choice. But, I would at least first find out the potency.
