The bowl, the biofilm, and what we threw away
Fatsy's chin issue started in autumn. Small black spots, irregular, along the line where the fur met the rim of his bowl. Not a rash — more like a stain on the coat that wouldn't brush out. We looked it up in the way you look things up at 11pm when you're half-convinced it isn't serious: quickly, wanting the answer to be nothing.
The vet called it feline chin acne — common, and often traced to plastic bowls. The surface harbours bacteria that the dishwasher does not reach.
What plastic does that ceramic doesn't
Plastic is porous in ways that are invisible until they matter. A new plastic bowl is sealed and smooth, but the moment food touches it, the surface begins to compromise. Teeth, tongue, the dragging of wet food across the rim — each leaves micro-scratches. The scratches trap organic material. Organic material feeds bacteria. Bacteria form a film that adheres to the surface, resistant to soap and water, which is not designed to penetrate a surface, only to move matter away from it.
Biofilm is the word for this. It is not a marketing word. It is what happens when bacteria colonise a surface and secrete a matrix of polysaccharides that anchor them in place. It is why you can smell a plastic bowl that has been washed and dried. It is why the scrubbing never seems to finish the job.
We threw the bowl away that week.
What replaced it was a stoneware bowl in an oak base. Glazed, non-porous, dishwasher-safe — the way our own bowls were. We had never thought about this before: that the standard we applied to our own dishes had no equivalent for the animal's. Our plates were ceramic because they lasted, because they washed clean, because stainless was for camping. His bowl was plastic because that was what a pet bowl was.
The stoneware went in the dishwasher. Fatsy ate from it on the first day without the circumspection British Shorthairs usually bring to any change of circumstance. His chin cleared inside a month.
We started looking at the rest of the kitchen differently after that. Not in the way of a sudden conversion — more like a recalibration. What else had we accepted without the standard we'd apply to anything else? The cutting board was plastic. The colander was plastic. The storage containers had been leaching since university. None of it was dramatic. All of it was replaceable.
That is, more or less, where this started. Not from an idea about sustainability or a commitment to natural materials — from a cat's chin and a word we'd never heard before. We now sell the bowl. We sell other things too: linen for the bedroom, glassware from a factory in France that has been making the same pressed pattern since before electricity, stoneware for the kitchen, candles poured by hand in Tallinn.
What they have in common is that they don't compromise. Not in the sense of lasting forever — everything ends — but in the sense that they do not quietly, invisibly fail the way plastic does. They age correctly. The linen softens. The oak darkens. The glaze on the bowl remains sealed.
Fatsy still uses it. He seems, as far as a British Shorthair communicates anything, indifferent to the upgrade. That is probably the right response. It is what the bowl should be: unremarkable to use, and not present in his chin.
