Is it blood?

One of my cats has either sprayed or sneezed something on my wall... Is there a product or test that might determine whether the 'something' is blood?

In the past two weeks or so, one of my cats has twice sprayed a wall with a reddish brown substance. I know the stuff isn't urine or marking spray - it has no smell. Also, the wall is directly behind the cats' favorite perching shelf - high up above my TV.

When I rub the stuff off with a damp towel, the towel sometimes comes away with red smears, sometimes brown smears. The smears on the towel have a slight iron scent to them - though that might also be the smell of my tap water.

Two of my cats are brothers and tend to have anal gland issues, so the substance might be gland-related. If so, that's a quick fix (one that a vet tech will be taking care of!). But if it's blood... Then that's a larger issue. None of the kitties are acting sick or have any sort of signs of sneezing/spraying blood (or anal gland-poopy stuff).

I've tried Google, but I think my search terms are bad. Do you know of any product/test kit that might help me determine whether this substance is blood?

It sure sounds like there's at least some blood in there. Hydrogen peroxide will foam up in the presence of blood, but it also foams up with a lot of other bodily fluids, too.

I say take a sample of the substance to your vet.

We're going through this with our altered female. In our case it's definitely blood in the urine. The vet says she's either sick (bladder inflamation) or she's crazy (stress is making her pee blood). He prescribed cortisone for 10 days and if she's still having problems she'll have to go on kitty Prozac.

Also, if you can get a clean sample (fresh, recent) you can sick it up into a syringe and have your vet test it. I don't know of any easy way to tell other than that.

Could it be flea dirt? Do either of your cats have fleas? Flea dirt is little black specks, but when it's wet it turns red/brown. Not sure how it would get sprayed on the wall.

Anecdote: I'm a vet, and a client with a greyhound was having a similar thing happen. The only thing I could find wrong with the dog was that it was infested with fleas. We treated the fleas and the blood spatters never happened again.

Luminol would probably work. It fluoresces in the presence of blood.

Response by poster: Luminol reacts to fecal matter as well as blood, so it's no help.

Peanut Butter Milkshake, it is definitely not flea dirt. I know what flea dirt looks like and, thankfully, none of the cats have fleas. They are indoor cats and I groom them often enough to know that there are no fleas or ticks present.

If it were blood in the urine wouldn't the wall stink of cat piss?

Best answer: It's winter, the dry season. I would assume it's blood and not necessarily of great concern. My sneezes sometimes have a little blood.

Best answer: My cat used to sneeze blood and snot in the winter. Vet said it was due to the dry air.

Response by poster: Jim, Halfwit and GregNog, thanks! The spatter does seem more like something from a sneeze than anything else - I hadn't been thinking about the cold, dry weather causing nosebleeds. The last time I had a cat who blew bloody snot, the cause was a tumor in her sinuses (and, yeah, it killed her).

My most favourite cat let me know he was in trouble by starting unusual urination, with blood present.

Turned out his urethra was blocked.

Sounds like a UTI. I had a cat with a horrible UTI that would spray on my bedroom wall, likely for attention. Sounds exactly like the same thing.
