Cat with Protein Losing Nephopathy, please help

In October I took Garfield to the vet because he had lost alot of weight. He used to be overweight.
So they drew blood, and did a urinalysis. And said that he had alot of protein, and sugar in his urine, but his blood was okay.
So at first they were thinking he is diabetic.
After furhter testing they said he was really dehydrated, and had a kidney infection. So he had to stay overnight, on an IV, they gave him a shot of antibiotic, and I had to give him pills when he came home.
The final diagnosis was Protien Losing Nephropathy.
Now 6 months later he hasn't put on any weight, but has a ravenous appetite, but normal thirst drive.
I feed him one can of Fancy Feat in the morning, and free choice Chicken Soup dry. If I feed him more canned he has loose stool.

I lost my cat Rusty to protein losing enteropathy (PLE). Is that what you're referring to? That said, my veterinarian said the fact that he did not respond to treatment was likely due to other underlying conditions. He was 15. It presented itself with a symptom that made him appear to be taking in large amounts of fluid subq. My only option was for blood transfusions, which in addition to the expense, may not have worked. Rusty was an extreme caution cat to handle, so we had him put to sleep when his condition deteriorated.

No, its PLN I guess theres 2 different diseases, of this condition.
I fixing to head to the vet with him right now.
Bad thing is, he's not even 3 yet.

Okay, I just go back from the vet.
He did a urinalysis, and said Garfield had alot of bllod in his urine, and white blood cells.
He said is was probably stress induced.
Sylvester our Bengal dominates him. So I need some suggestions for reducing Garfields stress.
I have 4 nueters, with 4 food bowls in differnet places, but I have 2 liter boxes both right next to each other in the laundry room.
I had 2 in the laudry room, and 1 in the bathroom, but the dogs always ate out of, so I took it away.
Please send a prayer that Garfield doesn't have any stones.
Thank you

IMHO I would suggest two more boxes( I use 18 and 30 gallon totes keeps all but huge dogs out)

Feliway spray or diffuser

Bachs rescue remedy

Ok, but any suggestions where to put them.
We have a small bathroom, and I have the basement set up for the breeding cats. The only place the nueters can go downstairs is the laundry room.

I have litter boxes all over the house. Bedroom, living room, den included. As long as it's not a kitchen, any room is fine.

What did your vet think about his ability to process protein and if a slightly higher protein food would be any good to offset what he lost? (just thinking that you could try a better wet - or maybe a kitten wet food)

So if kitty has blood and white blood cells in urine, that would indicate a urinary tract infection; hoping your Vet started Garfield on antibiotics then? Did he?

Have you ever thought of trying one of the extra large "hooded" litterboxes? I have 5 cats and 7 litterboxes in my basement. I have 2 extra large hooded ones, for the more "private" in the bunch LOL. A couple of mine will only use the hooded one. So if your kitty is feeling threatened, maybe having the hood to help feel more "secure" would help?

I agree with trying some Feliway diffusers in your home; your Americans can order them pretty cheaply on Amazon.com and I ordered some from www.absolutelypets.com and they were dirt cheap, and they have flat rate shipping to the U.S. and Canada...think it's only like $4.95 to the U.S. The best deal around.

Garfield is still at the vet. I'm going to stop by and see him, and find out when he can come home.
He is on fluids, and an antibiotic. He said he amy put him on either Torbe, or Buphenphone, to help he relax.
I'm going to stop at Walmart,a nd see what they have for litter boxes.

Dilly, check the private msg I just sent you. Your last msg there indicates that a recent urinalysis of your cat showed not only large protein but large sugar. Protein Losing Nephropathy is NOT going to cause glucose in the urine. With the weight loss, the kidney infection, the urinary tract infection, the increased appetite (sometimes diabetic cats have increased appetite), it seems to me your cat is diabetic. Please read the PM I sent to you. If there is glucose in the urine, it will surely be elevated in the blood. Did they check your cat's glucose level in the blood when they ran bloodwork?
