After everything I went through, that's exactly what I thought too.
After Milo died, I bought everything I could find.
First, a stainless steel bowl. Then a plastic fountain. Finally, a ceramic one.
I thought that as long as I changed the water every day, it would be enough.
But within two weeks, I noticed the same pattern:
Slimy buildup on the inside. A green tint around the edges. A faint odor that wouldn't go away no matter how much I scrubbed.
When I told Dr. Anderson, she simply nodded.
"That's exactly what I see every week," she said.
She explained that the problem isn't the material itself, it's that the water sits still.
"When water doesn't circulate, bacteria gain a foothold on the surface. It doesn't matter whether the bowl is made of plastic, ceramic, or stainless steel."
She continued:
"Plastic is the worst." It's porous on a microscopic level. Bacteria work their way into the material and stay there. You can scrub all you want, they'll still be there.
"Ceramic is better, but not perfect." Tiny pores allow biofilm to hide. And almost every ceramic fountain still contains plastic components inside.
"Stainless steel is the best material." She pointed to my stainless steel bowl in the photo. "But even that isn't enough if the water stays still. Cats can smell bacteria long before you can see them. To their instincts, it simply doesn't smell right."
That's when I realized I had replaced one problem with three new ones.
Every solution failed for the same reason:
Stagnant water. No oxygenation. Bacteria always finding a place to grow.
