About False Positive FIV Kitten

Many times when a kitten is tested for feline immunodeficiency virus the test results will show a false positive. This is why it is important that pet owners wait 60 days before getting their kitten retested. 

All cats that test positive should be retested because of the false positive.


Know that a year ago I took in an FIV feline immunodeficiency virus kitten because the woman who owned it did not want the cat, she did not want to learn more about the feline disease she told me to take the kitten or she would take it to the humane society. I knew that our area shelter would euthanize the kitten so I said I would take it and find it a forever home.


Finding homes for FIV kittens is difficult because, like the cat owner, people think FIV is a death sentence or an indication that the cat is sickly. Not one person wanted to learn more they just said no to me and would not adopt the kitten.


I ended up socializing the kitten with my adult FIV cat named Sam. This was not hard at all, Sam was one happy cat and the two became best of friends.


Know that the kitten had been to the veterinarian a few times, had gotten her spay and her rabies shot and all was well. But the following year when I was told that she need her annual shots I asked if it was necessary since she was FIV positive.  My veterinarian had no record of her being tested, so I told them of her history. I did not have the paperwork but the former owner was adamant about the cat's disease. I agreed to have her tested for feline leukemia and feline immunodeficiency virus. 

Both tests came back negative.


The kitten when she was tested showed a positive but it was false. I have no reason not to believe the former owner, as she was upset about the diagnosis of the cat and called me immediately when she had gotten the test results. Learn more about kittens with FIV and false positives here.

About False Positive FIV Tests

Quote: “Because few, if any, cats ever eliminate infection, the presence of antibody indicates that a cat is infected with FIV. This test can be performed by most veterinary diagnostic laboratories and also is available in kit form for use in veterinary clinics. Since false-positive results may occur, veterinarians recommend that positive results be confirmed using a test with a different format.  

Infected mother cats transfer FIV antibodies to nursing kittens, so kittens born to infected mothers may receive positive test results for several months after birth. However, few of these kittens actually are or will become infected. To clarify their infection status, kittens younger than six months of age receiving positive results should be retested at 60-day intervals until they are at least six months old.” End Quote Veterinarian Medicine Cornell education, health information on FIV   

Why is my Cat Vomiting - When to call Veterinarian?

It is common for cats to vomit, however not all vomiting is normal. Know that if your cat vomits when they are eating or right after they eat that this is a sign of illness and should not be overlooked. When a cat vomits when the eat it could be a stomach ailment, feline idiopathic cystitis or it could be due the muscle in the cats esophagus.

No harm is done to call your veterinarian and communicate your cat health concern. 

 I had a cat that did vomit when they were eating. I did not call my veterinarian immediately, instead I watched my FIV cat and found that when he ate he would vomit and knew that this was a red flag.  The veterinarian wanted to exam my cat and do blood-work. The diagnosis was a abscessed tooth.

One of my other cats would vomit at his food bowl, however this was due to anxiety. I was told that it might be a nervous condition, due to other cat pushing his way to eat at the bowl and not waiting his turn. It was suggested that I feed the cat in another room, that sharing the same food bowl may be causing the cat to feel anxiety and vomit. The feeding in another room was all that was needed. The vomiting stopped.

Renal Failure in FIV Cats

In November my cat's blood and urine tests indicated that he was in renal failure and I was told that this was an indication that the feline immunodeficiency virus had progressed.  That these FIV cats can live a long life but some cats will get sick when they are older.  Know that we rescued Sam in 2008, which was eight years ago and Sam is approximately 9 years old.  Everyone I know that has an FIV cat has told me that some cats will get sick in 5 to 6 years.

So when it came time for Sam's check-up to see how his kidneys were,  you bet I was worried.  Both my husband and I really love Sam our Siamese cat and feel sad that he is sick.   Sam went in for his wellness exam and lab work last Friday.  It took 4 days to get the results.

The veterinarian called for a urinalysis and blood evaluation.  Both tests came back with normal findings. Sam has been cleared of renal failure. In fact, at this time there is nothing wrong with him except that he has a diagnosis of feline immunodeficiency virus.   That is a virus he will have for the rest of his life.

I  had no idea that we could reverse the diagnosis of kidney failure but I think that before Sam was not getting enough water and now his KD canned cat food diet must be benefiting his health.  Going forward we will keep all of Sam's veterinarian appointments and will continue to feed him the KD prescription canned cat food.

Adopted Two FIV Cats

It is safe to say that I have been busy with my FIV cat's health concerns plus a few months ago I took in two FIV rescue cats.  The cats were sisters and both were a year old.  The family that asked me to take them was moving into an apartment that did not allow pets.  Had I not adopted the cats they would have been surrendered to our animal shelter and probably euthanized  

Three FIV cats are better than one

So I took the cats as a favor and in return, I was told that when their daughter got married in the spring she wanted the cats for her new home.   That sounds great but spring is a long way off and I had to socialize the new cats with Sam my FIV cat.

I had socialized Sam with a cat a few months back and that worked out well, but she was only with us a short time when my friend made arrangements for the cat to go live with her son.  Sam seemed to like the wind was taken from his sails.

My veterinarian advised me to not take in any more cats, because if Sam got into a fight that it would cause him to feel stressed and get sick.  I went against my veterinarians' recommendations and did socialize the two female cats.

I am not sure if Sam was lonely for a cat companion or what, but he welcomed those two girl cats like they were long-lost pals and the cats were happy to see him too.  There has never been territory marking or cat squabble.  The three of them just get along.  They sleep together, groom each other and play together. 

So how is Sam doing?  What I noticed is that Sam's overall disposition has improved.  I thought he was depressed but now he is back to his "ole self" meowing, talking to the birds in the morning from his window, and playing with the girl cats, we hear them playing with their toys and it is all good.

To tell you the truth, I think I got lucky that the cats were accepting of each other. It could have gone worse if there had been an alpha cat in the mix.

Cat with Kidney Disease Hates k/d Food

This is the follow-up post to Rushed my FIV Cat to Veterinarian as it explains how one day my FIV cat was fine and the next day he refused to eat.  

The attending veterinarian told me that my FIV cat named Sam has kidney disease and that this condition commonly occurs with late-stage cats with FIV.  Know that I am devastated because I had no idea that my cat was ill.  He had his lab work done in March 2015 and six months later he is diagnosed with kidney disease.  A real shock because he got sick out of nowhere.

Anyway, Sam is supposed to eat a special diet food for kidney disease in cats.  But Sam does not like the food and will not eat it.   Over the weekend Sam would meow for food and I would open a can of the k/d put some on the plate and mix a little water into the plate to make gravy.  Sam would be at my heels all the way into the room where I feed him, then he would sniff and walk away.  For four days he went without food. He would lick the gravy but not eat the food.

Monday we rushed him back to the veterinarian and they examined him and told me that they were going to give him a pill to stimulate his appetite and recommended that I start feeding him Royal Canin feline Renal LP.  Know that the veterinarian called me at home to tell me that many cats will not eat the k/d but that Royal Canin had a formula of food that cats preferred. 

So when I picked up my cat today I was pleasantly surprised because they gave me a 2.5-pound bag of the renal LP cat kibble to try.  Know that the appetite stimulant did work and Sam ate this food like he loved it.  

Sam is 8 years old.  

If you have a cat that has kidney failure and your cat does not like the special diet, you may want to try the prescription food by Royal Canin.  My cat Sam is so picky, and he really likes it.
