Question Details
Weight Loss In A Cat
by jenmercier - February 15, 2025    View Case Report
Yogi is a 10 yo MN cat with a constellation of issues.
The owners main concern is weight loss followed by rhinitis. He is thin with low muscle mass. Despite this, he is active and inquisitive with no signs of joint pain or mobility issues.

He also has chronic rhinitis. He is not audibly congested but did sneeze a few times in the exam and had thick mucopurulent discharge. owner reports his congestion worsens with stress. His history suggests he had calici virus 5 years ago and could be an underlying cause but he doesn't present like an active calici virus kitty.

He also has bouts of blood in the stool. Not diarrhea, no constipation, but short bouts of blood in the stool that appear to be brought on by stress as well.
Other things related to GI: his appetite isn't consistent. He will have days of eating good and other days with little interest but no sign of nausea and minimal vomiting.

Recent labwork raises concern for CKD and hyperthyroid. His Cr was 2.3 (which I think is extra concerning given his low muscling) but USG 1.050. His TT4 was 3.0. He is not an overt renal failure cat nor a hyperthyroid cat. He might produce more urine than is normal- 2-4 pee clumps per day. owner doesn't notice him to be PU.

Tongue is light pink to lavendar (owner says it looks white to her when he yawns) and pulse is deep, thin, wiry. Not fast.
His coat is maybe the slightest bit greasy.

He is laid back and a confident cat. He goes on camping trips and walks on a leash.

He did ok with most of the acupuncture needles but did react with BL20 (not sure if that was just my placement or it was actual "active").

Pattern DX:
Qi deficiency (SP, KID)- low motivation for food, azotemia, weight loss.
Blood/Yin deficiency given the weight loss.
Not much in the way of Heat signs except for when he has the bouts of blood in stool which I think is likely LIV overacting on the weakened Spleen.
The rhinitis could be entrenched Damp Heat but also secondary to lack of support from the middle and lower burners?
Because there is so much going on I think there must be some separation of Yin/Yang. TBO or perhaps Damp injured the Spleen to begin with?

Plan:
We are trying out home cooked food. Do you have a simple recipe suggestion? I've pulled some out from the TCVM Food Therapy text that I thought would fit.

Herbs: I have many thoughts but feel like I need a minor bupleurum formula and either a spleen qi tonic or Kidney Qi tonic

Maybe start with Dang Gui Shao Yao San to address Blood deficiency but also open the triple burner and support the spleen
and either Six Gentlemen or Rehmannia Eight (the KPC formula?). Six Gentlemen may be preferrable to start for appetite.

Cats are so tricky! This owner is very committed so I am hopeful to be able to make a difference.

Thanks,
jen

Hi Jen,

I'd be tempted to try Bu Zhong Yi Qi Tang, and something for the nose - maybe Cang Er Zi San, which you may have to source as teapills.

So far as how I interpret things:
- Yin deficiency is only a cause of weight loss if the GI is sound and appetite is strong. Otherwise, we are looking at some issue with the Spleen
- the nasal issues suggest Wind Damp invasion, which can occur in turn from depleted Wei Qi, particularly given the cat has been prone to other infections. It's important to resolve this sign as the rhinitis may hamper the sense of smell, causing the cat to eat less
- since Wei Qi is made by the Spleen, we can address low appetite and GI weakness by targeting one organ. A formula called Yu Ping Feng San does that, but then there is the occasional blood in the stool. That makes me wonder if you should try Bu Zhong Yi Qi Tang as your Wei Qi tonic instead. It also has the benefit of improving assimilation while reducing blood loss. Additionally, BZYQT helps potentiate Wind expelling herbs, so it would make the Cang Er Zi San for the rhinitis work better. Lastly, BZYQT is a good call for animals aggravated by stress (i.e., taxing of the adrenal glands, which it supports).

I wouldn't place too much emphasis on the creatinine reading when the USG is so high.

If the greasy coat gets worse on the BZYQT, then you know you need either San Ren Tang or Wei Ling Tang to support appetite and normalize GI function. SRT does help expel Wind Damp from the nose. Both BZYQT and SRT can present with the deep toned pulses

Hopefully one of those ideas helps! Let us know how it goes!

Thank you!
We have done a ton of labwork since I posted. Some interesting changes. Hct has dropped from 36% to 28% (October to now). Anemia is normocytic, hypochromic, non-regenerative.
Cr still 2.1, SDMA improved to 12.5 from 18. USG still 1.049, UPC normal.
Cholesterol normal, thyroid normal
Fecal negative, FeLV/FIV negative, tick and flea PCR panel all negative, maldigestion panel normal (cobalamin/folate levels normal)

So there could be occult flea/tick borne pathogen, and/or URI pathogen but what I can confirm is development of anemia and persistent Cr elevation. An ultrasound could help determine more with GI and renal but that is the last test I think I have available.

Does any of this change your thougts? I was also feeling like Spleen deficiency is at the root of this.

BZYQT treats Spleen deficiency, so it remains my top recommendation right now, as it also supports bone marrow synthesis of red blood cells

The creatinine is of zero concern when the USG can get so high. It's a normal finding

What do you think about Bi Yan Pian as a Wind Expelling formula for the rhinitis?

It's okay, I guess. There are a lot of additional things in there that can work against or at least not contribute to your goals, but if that's all you can source, then I guess give it a try.
