Malabsorption in Cats

So I took my cat to the vet, he was de-wormed cause he had tapeworms for about a year, but the deworming didn't change the outcome: he's always hungry and he is skin and bones, even losing some fur/fur thinning. He use to have blood in his stool as well, the blood stopped when we put him on salmon cat food but he's still not gaining and still always hungry. I feed him 4 1/2 cans a day... no improvement. The vet also gave him a blood test and found that his blood is normal (and hasn't been much help since then). The cat is fine in every other area (energetic, ect)
P.S. he has to be on urinary tract food because he has had blockages a few times.
Also if he eats a new type of food, or even over eats reg food he will have diarrhea and vomit. Oh and his rectum swells up when he goes, but it goes back in when he's done

hi i have a 1year old domestic cat- about 3 months ago he started to get very skinny and hungry all the time - he is has regular flea and worming treatments. He often will poo outside his litterbox and sometimes the faeces looks undigested. Sometimes it seems like the need to poo comes upon him all of a sudden and he'll just poo on the floor, its not diarreah So i took him to the vet - they did a number of tests with bloods and urine, we gave him antibiotics in case it was a bowel inflammatory issue but no improvement. Hes happy enough, just skinny and hungry - i feed him twice a day and he has access to dry biscuits all day. The vet costs were substantial and the next set of tests are over $800
Do gooders in my street are threatening to call the police for neglect he looks so skinny
What can i do

My 13 yr old cat Ginger has been steadily losing weight for several months. He lost two more pounds in the last two months and weighs 6.8 lbs now. He eats, but not as much as when he was younger. I started to put out less food about a year ago because he and his brother were throwing up, but I have gone back to leaving out a full bowl of kibble and a plate of wet food all day. Ginger cries a lot at night and walks up and down the halls wailing He also has been biting/pulling out his fur. He has large patches of fur missing from his belly and legs. His tummy rumbles quite a bit and he has gas but no diarrhea. We did a fecal test for parasites, two rounds of blood work to rule out diabetes and thyroid issues, X-rays of his heart, lungs and stomach. I tried giving him probiotics and digestive enzymes. We don’t know what could be wrong with him. Next I’m having his blood tested for malabsorption and the vet thinks we might have to do a sonogram too, but no guarantee of a diagnosis. Anything else you can suggest? I’m getting desperate to find out what is wrong with him. Thank you!

My 15 year old female cat had loss her appetite and in turn lost weight. She is hyperthyroid but managed with tapazole for a little over 2 years. Vet did a full blood panel and all came back in normal range. She suspects GI cancer but does not feel any masses. I declined sonogram and just figured we would monitor her for the time being. Since a month ago when syptoms started, she has now regained appetite but still not gaining weight. Now that she is eating again she is now having diarrhea. It is tan in color and very smelly(no blood). No vomiting. She is still drinking and eating well even though she is having the diarrhea. Vet suggested either b12 shot or antibiotics with a probiotic. I am going to try the antibiotic and probiotic first and she said if no improvement in a week to come back for b12 shot. The confusing thing is that she lost appetite but is now eating well. She is frail looking but still meows for food and looks like her self except for being so tiny. Is it possible that it was something else and never GI cancer? Is there something else we should look at or try? I didn’t want to do the sonogram because she has always been a temperamental cat and they would probably have to put her under anesthesia to do the sonogram and in her frail state I don’t think it would be good.

My cat is 16 years old and is always ravenous, wants to eat constantly and yet is not gaining weight. His thyroid has been checked and is fine but we can't afford all the expensive tests. Is there something we can give him in his diet that will help him absorb the food and nutrients?

My 10 month old cat has suffered from mild to severe diarrhea for 6 months. In that time he's lost a significant amount of weight and is often lethargic and cold. He has sustained a great appetite, but he just doesn't get better. We've tested for parasites, he's been on several courses of antiobiotics, he's on daily probiotics, his blood work is inconclusive. The vet says it points to FIB but that test is inconclusive as well. For the past week he's been listless and weak. He still eats well but I've also stopped him from eating cat litter. What do I do next?

my cat is 20 years old and has developed an urge to eat constantly. i am concerned that this might be a sign of her getting ready to die? when she urinates it is a large amount. she also vomits on a regular basis

My boyfriend and I are looking to move in soon, and he wants to bring his cat with him. And I've been concerned for this cats health since day on. She was around 8 years old when I met him (she's 10 now) and she was so small and skinny I thought maybe he neglected her. But she eats fine .
Unfortunately soon after meal time, she has to use the bathroom . And it's horrible. Her stools smell so awful your eyes water, you start to gag and you have to flush it down the toilet or you throw up. She also vomits a lot. They've just accepted it but I'd like to get her back into decent health before we live together because I can't handle her litter box visits. I would love an opinion about where to start.

I have a 19 year old cat who eats very well and is active but is getting thinner and thinner. Is it possible that she isn’t absorbing nutrients from the food? What can I do?

I have a rescue kitten (approx 9 mths) however looks more like 4 mths. She isn't putting on weight and so is not growing, upon advice we got tests done, no issues regarding liver/kidney function, no protein in urine, stools are normal, she doesn't have diarrhoea, nor is she constipated. The only thing that the lab suggested was that it 'looks' like she could have malabsorption. She would eat you out of house and home, her appetite would rival any adult stray cat but weight doesn't stay on her.

Based on the malabsorption theory, the vet recommended trying her on specialised wet and dry food for this and sachets of granules specific for malabsorption, for 2 weeks we separated her, gave her smaller portions more often, but she wasn't eating much and no evident weight gain, I then put her onto her usual shop food but still gave her the granules and kept her separate from the other cats to keep track of her intake, she seemed to be bulking out a little, however some says she still looks very thin.

She has no energy, except when food is put down in front of her, she takes colds easily, I can see she is run down, but I am not in a position to get test after test done in order to keep ruling things out. Is there anything else I can try to build this kitten up, she looks miserable, they also ruled out dwarfism.

My 14 year old kitty ,started chewing on white phone charging cords a year ago . I took her to the vet . She said she had a severe hyperthyroid . She has been on meds for it ever since ,she is now taking the highest dose possible . Mid way through she developed malabsorbtion. The doc has tried everything from antibiotics to steroids. She has frequent diarrhea, and a voracious appetite along with drinking water constantly. Nothing is working . I asked my vet if she could possibly have a cancer . All she did is shrug hershoulders. I am at a loss . I feel the only thing left is to put her down . She is suffering. Please advise..

My kitten (10 months) is a Bengal. He eats like a little pig and has diarrhea occasionally. He has not gained any weight in the last month or two. He does not show any signs of having a parasite such as a tapeworm. He was just prescribed metronidazole by the Veterinarian but am not sure if that will help any. I am unsure of what my next step with him is.
