Does canned food turn red at night
cindigal posted:
It's probably nothing, but it could be a problem. I give my 2 cats Friskies canned food, different flavors in the pate, chunks or shreds. The other night i saw some red stuff in the bowls. Since both cats feed from the bowls, one in particular like his canned food. I gave them shreds that time. I saw red stuff within the food. Usually at morning if they didnt eat the food I dumped it out and give fresh. Today i gave them a different flavor. What is with the red color in the meat, could it be the canned. Hoping that is nothing wrong with cats. If they were sick, would they still eat, drink water, play and run with the other cat if he was sick..?? I really want to get better food for them but at my budget the higher priced food i couldnt buy. Any theories about the red in the bowl would be appreciated.

I noticed the same thing with friskies.Its like a deep red dye,Searching online I cant find anything.Usually only happens at night but lately Ive noticed it in the daytime.Did u come up with an answer as to why it happens?
rohvannyn responded:
So you are only seeing the red color at night? If that is the case, perhaps the color in the food looks different under house lights than it does under daylight?

Yes i just noticed this recently ... i opened cat food yesterday and i went to give it to cat and it is bright red/pink like the red/pink that you get on your teeth when you chew those pills to show plaque.. see picture here
rohvannyn replied to kmathews2's response:
So, does the exact same type of food look different when you open it at night versus during the day? Are you opening it under artificial light, natural light, or a mix?

Different kinds of light bulbs can make some colors look very different than each other. Try looking at something under fluorescent light, incandescent, and natural light, and you will see a big difference.

I'm having the exact same issue with cans of wet dog food, from two different brands, Iam's high-calorie and Newman's Own grain free.

It is decidedly not a lighting issue. It looks like someone poured bright-red food coloring on the food, and kind of looks like mold but isn't growing like mold. I have photos here, both in direct sunlight (N.O.) and regular incadescent (Iam's).

I suspect some sort of contamination from the house, but I have no idea what it might be. The Newman's Own people were very interested at first, but then they said it was likely just oxidation and stopped talking to me.

Thing is, I've never had this happen before and I've been using N.O. for more than a year now, as well as other wet dog foods.

I'm more concerned that there's something in the house itself rather than the food, since it's happened all of a sudden (just in the last week).

I have just started having same problem this week with Friskeys Filets, chicken and gravy. It is only canned food she will eat and Science dry food. She does not eat much and never has. She is a Siamese and 12 yrs old. Has nevet been sick! But, vomited this up before I noticed it. I stired the can up and looked very close at it and ....nothing but usual appearance and smelling like normal. I even took everything out of can and put in pyrex bowl. When i looked next through out all of it. I had thought that she had cut her tongue on can. Then, I noticed it stained my sink when I was putting in garbage disposal. What states was other cans bought. I in Ohio. Will never buy again. Hope to get answers.
rohvannyn replied to kitkatnip0918's response:
The food could have oxidized, which is harmless, but I can still understand your concern. You may want to call the manufacturer and ask them about it. I've found they are usually pretty open to questions. Sometimes food dyes can change with exposure to the air, and it sounds like this happened here.
undefined responded:
Today I came from lake gorge and I see that in my cats canned food (friskies chicken and salmon dinner in gravy sherds) that's there is something red, first I thought it was blood but the I realize its like a cherry jammcolor thing and it does not even have a smell to it, all I wanna know is that its not blood or and infectiom
rohvannyn replied to 200057910's response:
First, cat food can't get infected because it isn't alive. Second, it's sounding like some of these cat foods oxidize (which means they might turn red) on exposure to air. We put a lot of different dyes etc in cat food to make it good looking to humans. I've never had a problem with Friskies, but I have it seen it change color somewhat after it's been sitting out a while.
