meat only diet, alkaline urine

I really hope someone can tell me how a urine ph could be alkaline if all they eat is raw meat & canned food with no grains. I am floored!

I can't tell you exactly how that would happen, but one thing that affects pH is how often they eat.  Evidently about 6 hours after a meal, the urine pH starts to go up, so if you checked the pH more than 6 hours after she ate, it could be this natural rhythm.

Another thing could be the contents of the "no grain" canned food, because many manufacturers have substituted non-grain items for the previous grains in wet food, so read the label and look for potatoes, peas, pea protein, carrots, sweet potatoes, any kind of starch, anything not meat and fat, because vegetables and other carbs will produce alkaline urine, whereas meat and fat produce acidic urine. 

If you are concerned about the pH allowing the formation of struvite crystals, there are a couple of things you can do.  One is the emergency short term vinegar treatment. You can use  Bragg's Organic Apple Cider Vinegar (unfiltered, with the "mother" bacteria) mixed with distilled water, 1 part vinegar to 4 parts water, and administer 1 cc. by mouth every half hour until the pH comes down to 6.5.  Another thing you can do is to buy natural L-methionine from a health food store and add a tiny bit to each meal, very little, like how you would salt human food.  This worked well for my girl when she was having problems with alkaline pH early in her recovery. 

I forgot to mention no veggies either. She was on Weruva & now on Tiki Cat. They're both simple foods, meat, broth, supplements.

I am just floored as to her ph being 8.0. Eating raw meat every morning & then canned the rest of the time.

The urine was collected about 4 hours after her meal so it was in the time frame you mentioned

She's at the vet now getting a dental, so while she's under they're going to do another urine sample. I'll know today what it is

Wow, 8.0 is definitely struvite territory.  Let's hope that perhaps your test strips just went bad.  The only other thing I know of that affects pH is stress.  From one study I read, "it has been reported that the urine pH of a cat increased by 1.4 u when transported from its normal home to a veterinary clinic. Buffington and Chew concluded that the most likely cause was anxiety-induced hyperventilation (excessive panting) (alkaline urine is known to be caused by hyperventilation)."

When I took her to the vet, she didn't meow once. Wasn't panting, breathing heard, nothing. When we got there & was waiting for a room, I reached my hand into the little cage, I could feel her shivering. After a few minutes of me touching her & scratching her, it stopped.

See my confusion??? I feel I've fed right, meat only which is what cats natural diet is & her blood work & urine are totally off. I guess food doesn't fix everything, she might have had something from the time I got her, the County Animal Shelter doesn't to any prelim bloodwork or anything. I even called them today just to double check, when she was a baby she had a hernia so she had to get surgery, they didn't even check her blood.

I guess this is another learning experience, whenever you get a kitten, after about a year I would get a full blood panel so you have a baseline to work with. My girl is about 2.5 years old now & I don't know how long she might have had a problem. She totally act normal, pees & poops fine, purrs, runs around, acts like a normal healthy kitty.

I have noticed her being at the water more in the last couple of months, I thought it was from all the raw food making her thirsty. I don't add as much water as they tell you cause my cats don't like soup.

Just got a call from the 2nd urine, came back normal so she doesn't have any kind of infection. They look for bacteria & crystals, nothing. YAY!

Great!  I DO think that the "shivering" is a sign of stress, and you calmed her by stroking her.  She may not pant or meow, but she shakes with fear, s probably the less you take her to the vet, the better she will be. 

Some cats are just more prone to these things than others regardless of diet. However, it seems odd her pH would be high but no crystals. I'd probably request they run the test again to make sure there wasn't an error. You might want to look at giving a supplement to help with urinary health. Slippery elm would be a good choice/
