Frustrated. Cat with flutd

My kitten is 6 months old and just 2 weeks ago started urinating blood all over the house. I took him in and the vet put him on antibiotics but that did not work. I am thinking that this started when I switched his cat food.
Anyway, I am gone at work all day and the kitten is living in the garage right now because I can't have blood all over the place in the house. The garage smells so bad btw.
I do not know what to do to get him to stop urinating everywhere. I am a single mom and cannot afford the expensive urinary cat food. Are there any cheaper options? Is there anything else I can do other than just change his food? I want to bring him back in the house

He's still peeing blood???? That's not normal ever. Can you take him ASAP to another vet. As far as food, I would avoid any cat food with fish in it. Also try to push water consumption and if you can switch to all wet food that would be good. I think the blood is a concern though....

The vet said that cats with flutd will urinate blood. We did a urine sample and then he was in antibiotics for 7 days. I just talked to the vet and she told me that he had flutd and that she would send info.

I am so very sorry your kitty is going thru this. Somehow, please get him back to the vets. The litter box problem should resolve itself once you get the blood under control. It is painful for him to urinate which is why he's not using the box. He is associating it with pain right now. He really should be on script food until the urine is totally clear. Barring being able to do that, can you switch him to totally canned food, no dry kibble at all. Fancy Feast pates are fairly good, no fish flavors or anything with seafood in it. Pet stores like Petco carry Purina UR, they are 3 oz cans for .99 at my local store. I know that is still expensive as your kitty probably will need to eat several cans a day. If you can do that even for a short time, that may help. Also, check the prices on Chewy.com, many times you can get food cheaper there. Regardless, please get him back to a vet ASAP, he could easily block and die in awful pain. Prayers to both of you.

There is a lot of info on FLUD cats on www.catinfo.org    The site is by a vet, there is a lot of info on this condition, please do read all of it. Several months ago I adopted my boy from a local shelter with this diagnosis. We got him under control with the script foods. Now I"m switching to canned with low magnesium and phosphorous. The right foods are really the key to resolving this and keeping it under control for his lifetime.

With a young cat, the cause is NOT usually bacterial, it is usually crystals in the urine that irritate the bladder like little microscopic shards of glass.  In most cases they are struvite crystals, and they cannot form when the urine pH is slightly acidic.  The normal urinary pH of a feral cat eating a feral diet has been tested at 6.0 to 6.5 (neutral is 7.0 and alkalie is anything over that.) 

Diets consisting of muscle meat, fat, and very low (less than 10%) carbohydrates naturally create an acidic urine pH, so struvite crystals will dissolve and new ones will not form.  Diets consisting of plant proteins and carbohydrates produce an alkaline pH and struvite crystals are very likely to form. 

You said the problem started when you switched his cat food so I think that is probably a big red flag.  What were you feeding before the problem?  Read the ingredients.  What did you change him to?  Read those ingredients and compare.

You do NOT need to switch to expensive prescription food.  In fact you can give him a better diet  for less money by using canned foods made up of primarily muscle meat protein and fat and with little or no carbohydrates.  Believe it or not, the Friskies Pate varieties, especially Poultry Platter, fit that bill.  Avoid all the ones with the shreds and bits and pieces and gravy -- just stick to the Pate varieties.  Same thing is true with Fancy Feast and Sheba.  Also, if you have a cat with FLUTD, she should get little or no dry food.  There are NO low-carb dry foods, they need starches to hold them together.

I will send you the story of "Saving MJ" which is lengthy and detailed but tells of exactly what I did to save a female cat who was about to be put tl sleep by a no-kill shelter just because she was suffering so much with recurrent bouts of painful bladder inflammation and blood and the vets were unable to cure her with their antibiotics and prescription DRY food.  She has been problem free for 1 1/2 years now, controlled by diet alone.  She eats the canned foods I mentioned above plus some from Tractor Supply, their 4Health grain-free chicken (WITHOUT gravy, they have both kinds) and 4Health grain-free turkey & giblets. All the details are in the story.  You CAN cure your cat so start now.  If you have ever had cystitis, you know how incredibly painful and uncomfortable it is.  Don't let her suffer through this.

Thank you!!! I am calling a new vet in the morning. I called a bunch today to ask for pricing and found ut that I was paying twice as much as I should have. The cat was on clovamax 15 ml for 7 days and I paid $68.  All of the vets that I spoke to told me the cost was $30-32. The xray, urinalysis, etc was way over priced .  I was told that the xrays and urinalysis that I needed would be $560 and I had already spent $300. 

Anyways, I will be taking him back in and I already changed his cat food. We went from friskies which is what he got at the humane society to the costco organic brand. It is made with sweet potatoes, chicken... I thought I was doing something good for him. Hopefully it will get cleared up soon so that he can come back inside. 

NO kibble. Wet food, wet food, wet food, more wet food. A cat that young should not having urinary issues, this is more than likely related to food. Kibble is dehydrating and triggers urinary issues. Low quality kibble contains corn, wheat, soy, and starchy veggies (like potatoes) that cats do not need. Cats are obligate carnivores. They need meat, meat, and more meat, everything else is a cheap filler. Look into buying a water fountain to encourage drinking. 

As everyone else said, this cat needs to be evaluated by a vet again and may need another round of antibiotics. Make sure the litter box is cleaned regularly and look into buying a bag of cat attract litter to help get him back in the habit of using the box.
