Valentina Mallozzi bought the container because it was supposed to keep her pets out of the food.
In July 2025, her seven-month-old kitten Ace got into it anyway. He nudged the latch, climbed in, and the lid swung shut behind him and relocked, forming an airtight seal. He suffocated inside.
On October 22, Mallozzi filed a class action complaint against Iris USA in Pennsylvania federal court. The suit alleges that the company’s airtight pet food containers carry a design defect, that Iris marketed the very feature that killed Ace as a safety feature, and that the company knew.
The mechanism, and why “pet-proof” was the problem
The container has a downward-swinging latch. Iris markets that latch as the thing that keeps animals out of the kibble.
The complaint alleges it does the opposite. A determined animal, and cats are the relevant animals here, can nudge the latch open from the outside. Once the lid is up, an empty or half-empty bin is an inviting place: dark, enclosed, and smelling strongly of food. The cat climbs in. The lid rebounds. It relocks.
And then the same seal that keeps oxygen away from the kibble keeps oxygen away from the cat.
A small animal in a sealed container can suffocate within minutes. That is the part almost nobody has internalized, and it is why this is not a story about carelessness. There is no window in which you notice, no yowling you hear from the next room. It is fast, it is silent, and the container looks exactly the way it always looks.
The report that came out first
This is the part of the story that turns a tragedy into a lawsuit.
In March 2025, months before Ace died, the Center for Pet Safety published a report, produced with the nonprofit Prevent Pet Suffocation, evaluating airtight storage containers. It warned consumers directly. It identified Iris-brand containers as being among the most hazardous, singling out the latch and the foam-lined lid. And it noted something that punctures the most common reassurance owners give themselves.
“While it seems intuitive that a pet would simply be able to push the lid open to escape the closed container, the data indicates otherwise. Based on reports received, pet owners believe pets became disoriented and/or were unable to escape the closed containers due to depth of the container. Deceased pets were found in both latched and unlatched containers.”
Read that last sentence twice. Deceased pets were found in unlatched containers. The lid does not need to lock for an animal to die in there. A cat at the bottom of a deep, dark, smooth-sided bin, panicking, cannot get the leverage to push a lid up over her head.
CPS also flagged that there are no mandatory warning labels on these containers. None. And according to the complaint, Iris does not appear to have changed its manufacturing or added any warning since the report landed.
The suit alleges Iris knew through the CPS report, through direct customer complaints, and through social media. On the Prevent Pet Suffocation Facebook page there are memorial posts for pets who died in these containers, including one for Ace. The comments are other people saying it happened to them too.
CPS says the majority of these cases involve cats.
We have to correct ourselves here
This is uncomfortable to write, and it needs writing.
The Pet Times has published a dog food container guide that tells readers to buy for the airtight seal above everything else, on the entirely valid grounds that oxygen turns the fats in kibble rancid. That advice is correct about food freshness. It said nothing about suffocation, because we did not know to.
Both things are true at once. An airtight seal protects the food. An airtight seal is also what kills a trapped animal. We are updating that guide, and if you bought a bin on our recommendation, this article is the other half of what we owed you.
“The whole design brief for these bins is ‘nothing gets in or out,’ and we all nodded along because we were thinking about oxygen and mice,” says Dr. Nina Kohl. “Nobody was thinking about a curious seven-month-old kitten, who is small enough to fit, smart enough to work a latch, and completely unable to lift a lid off her own back.”
What to actually do tonight
You do not need to throw the container out. You need to make it impossible for a cat to end up sealed inside one.
Store it where the cat isn’t. A closed pantry, a utility cupboard, a garage, a room with a door that shuts. This single change removes almost all of the risk, and it costs nothing.
Never leave the lid open and unattended. The dangerous moment is not when the bin is closed. It is the thirty seconds you walk away to answer the door with the lid up.
Defeat the seal. If the bin lives somewhere your cat can reach it, do not rely on the latch. Put something heavy on the lid, or wedge it so it physically cannot fall shut and reseal.
Look inside before you close it. Every time. This feels absurd until you have read one of those memorial posts.
Watch the ones that are the right size for a cat. A bin that comfortably holds a curled-up cat is the hazard. A bin too small to climb into is not.
Keep the kibble in its original bag inside the container. Worth doing anyway, since the bag carries the batch number and expiry you will want if there is ever a recall, and it slows fat oxidation. It also happens to make the interior a less inviting place to jump into.
If you have lost an animal this way, Prevent Pet Suffocation collects these reports, and the CPS report exists precisely because people reported.
What’s still unresolved
The lawsuit is a complaint, not a verdict. It alleges Iris violated Pennsylvania’s Unfair Trade Practices and Consumer Protection Law, committed negligence, breached warranties, and engaged in deceptive marketing. Pennsylvania product liability law requires manufacturers to design products that are reasonably safe for their intended use, and the suit argues that a container animals can climb into and be sealed inside does not clear that bar. Iris has not been found liable of anything, and the case has not been decided.
What is not in dispute is the physics. A sealed, airtight, deep-sided plastic bin is a hazard to a small animal, whatever brand is stamped on it, and the industry currently ships them with no warning at all.
Ace was seven months old. He was doing exactly what a seven-month-old cat does, which is get into something he shouldn’t. The container was supposed to be the thing that stopped him.
