Eighteen year old female DSH has.. opted? to change her diet.

I'm a Canadian so I'll put measurements in both grams and ounces.

For the last couple of days, she's only eating about 75g (2.5oz) of wet food a day, instead of 100-115g (~3.5-4oz) plus 2-3 oz of dry food a day. The dry food bowl was always topped up (with a scoop) if the bottom of the bowl was visible, we never gave it much thought so no idea how much she was eating.

About a year ago, I started feeding her wet food during my breakfast in lieu of giving her milk. She nagged, cajoled and otherwise annoyed me into feeding her around 25g (0.9 oz) of wet food four times a day. She's lost some weight over the last few months, which I attributed to higher quality food. She weighs just over 10 pounds as of now.

Saturday morning I noticed there wasn't much poop in the litter box, and then found that she hadn't eaten any dry food for at least a few days. Now the most she's eating out of a serving of wet food is 20g (about 3/4 oz) - more often less than 14g (half an ounce). I've been weighing the dry food as well, and she hasn't touched it at all.

She's drinking less, but perhaps without dry food that's normal.

The reason I have these measurements is because I had to "dial in" an amount that she wouldn't scarf'n'barf. I was ok with her doing that with the dry food but she wouldn't clean up the wet food and its expensive :)

Because it was supposed to be fed as snacks, I have several different brands of grain-free pâté-style wet food on hand, and she won't really eat much of any of them - warmed, room temperature or cold.

She pooped while I was watching this morning. She didn't strain and it was normal, if a bit small.

She's pretty sedentary, she is after all 18 and has some arthritis-like symptoms. We just got a new bedroom chair, which she has claimed as hers.

Do I need to hustle her to a vet, or should I keep trying different foods while I try to find a good vet? Her original vet retired, and the interim vet we tried was more like a hippie kindergarten teacher than a doctor.

I'd take the cat to a vet. Elderly cats can have any number of health issues that can cause a poor appetite. Make sure the vet does blood work. Is there any other vet in the area you can go to? If you're not satisfied with the current vet, there's no reason to stay with him.

This is definitely cause for a vet visit.  It could be her thyroid, which is treatable.  Be sure to ask them for the senior blood panel which will test kidneys, thyroid, and also check for diabetes.

Vet visit:

Says she looks really good for 18.

Says mild early stage kidney disease based on bloodwork, nothing else overly exciting. Didn't think anything in the bowel was too large to pass, and an enema resulted nothing out of the ordinary. Gave her some lactulose which resulted in a little bit of diarrhea. Sent us home with some expensive canned low protein food and some very expensive lactulose (which I have not used due to aforementioned diarrhea, and further normal behaviour). Doesn't expect hypothyroid, but couldn't test due to expired supplies.

(Urea 20 mmol/L, Creatinine 310 µmol/L, BUN 16, Glucose 11 mmol/L, phosphorus 1.5 mmol/L (all rounded)). Dr says Glucose and a few other factors are probably the stress visit. She does not like car travel.

Current:

She still won't eat much. Drinks less, likely due to not eating dry food.

I've tried everything I can think of short of turning the wet food into literal soup. Cold, room temperature, body temperature, extra liquid, big chunks, little chunks, mashed flat, different types of plates and bowls, elevated bowls, tried feeding her off a fork and out of my hands. She eats about 1/2-3/4 oz and then goes away, cleans her face and then heads for one of her favourite sleeping spots. Three or four times a day.

She occasionally does sort of burp, and then swallows a few times. This happens at random times, not specifically around feeding. Acid reflux or something? According to some reports kidney disease causes nausea. Anything I can do about this? I'd try some calcium carbonate except I doubt mint flavouring is going to be to her liking :)

She's getting a max of 2.5oz of wet food a day, which I don't think is enough for a 9.5lb 18 year old cat. Sadly my scale has turned out to be inaccurate so I'm unsure how much weight she's lost.

She's more subdued than I expect, and less vocal. She's not hiding away like she's mortally ill, but she's not climbing on me demanding scratches nor being underfoot when I'm trying to get things done.

Ideas?

Low protein food? Ugh. that's such an outdated theory about treating CKD. Especially a cat in the early stages should be in a high protein low phos food, and NO kibble, all wet food only. Take a look around at http://www.felinecrf.org/ which is well known as the "bible" for CKD cats. 

Also if you have a facebook join this group and post a copy of your labs, they'll direct to towards everything else you need to know. Yes, CKD can cause nausea.

Thanks for the link, am trying Slippery Elm Bark powder now. Found a good source for "wild-crafted", was not expensive.
