• It's a tasteless white powder that dissolves completely in the fountain water. Your cat drinks it without knowing it's there. Taurine is an essential amino acid cats cannot produce themselves — it supports heart and kidney cell health. Co Q10 fuels cellular energy in kidney cells. One scoop per day. That's the entire routine.

Did You Know Over 70% of Cats Are Chronically Dehydrated?

Cats evolved to get moisture from fresh prey — not still water in a bowl. When water sits still, their instincts flag it as unsafe. They drink less. Their urine concentrates.

Concentrated urine is where crystals form. Crystals are where blockages start. Blockages are where the $3,000–$7,000 ER bills come from.

This instinct leads to lower water intake. That puts your cat at risk for:

• Painful urinary crystals

• Chronic kidney damage

• Costly, life-threatening emergencies

The BiologyPets fountain uses a flowing faucet-style stream that mimics the natural water sources cats instinctively trust. Cats who switch to BiologyPets drink more water — and the water they drink is free of the minerals that cause the problem in the first place.

"Linda Davis 2h ago I've tried 3 different water fountains for my cats and this one takes the cake. Previous fountains got slimy pretty quick — this one doesn't, which is a huge plus. I have 8 cats and at least 5 are picky about their water. The ion-exchange filter is what sold me. Filters and cleaning tools included, putting it together was quick and easy. Highly recommend! 1.1k 43 Comments Like Comment Share"

"Martha Kowalski 1d ago This is the best cat water fountain!! I've owned several through the years. Stainless steel is so much better than plastic!! My vet suggested a stainless fountain approximately 10 years ago. It helps maintain good kidney function as your cat ages. The ion-exchange filter removes the minerals other fountains just let through. I give this fountain 5 stars and highly recommend. 2.3k 67 Comments Like Comment Share"

"Our four-layer filtration removes what other fountains miss. The ion-exchange stage extracts calcium and magnesium — the exact minerals that precipitate into struvite and calcium oxalate crystals — from the water before it reaches the bowl."

"The free Taurine + Co Q10 supplement supports kidney cell function from the inside. Taurine is essential for feline heart and kidney cell integrity. Co Q10 fuels the mitochondria in kidney cells. Together they work with clean water — not instead of it."

"Owners report that their cats start drinking within hours. Not days. Hours."

FAQs

What is The Mineral Crystal Cascade?
- It's the chain that leads to crystals and kidney problems in cats. Tap water contains dissolved calcium and magnesium. Your cat drinks it. Those minerals concentrate in the urine. They crystallise. Crystals cause blockages and kidney damage. Biology Pets' ion-exchange stage interrupts that chain before it starts — pulling those minerals out of the water before your cat takes a sip.

How does ion-exchange filtration actually remove crystals?
- It doesn't remove crystals — it removes the minerals that form them. The ion-exchange resin performs a chemical swap: it pulls dissolved calcium and magnesium out of the water and replaces them with harmless sodium ions. Less calcium and magnesium in the water means less of those minerals reaching your cat's kidneys. That's the mechanism. No other fountain on the market includes this stage.

Is the Taurine + Co Q10 supplement safe for all cats?
- Yes. Taurine is an essential amino acid that cats must get from their diet — they cannot produce it on their own. Co Q10 supports cellular energy at the mitochondrial level. Both are well-studied, naturally occurring compounds. The powder contains no artificial fillers, no sugar, and no flavoring. If your cat has a specific medical condition, check with your vet before starting any supplement.

My cat only drinks from the tap. Will they use this?
- Almost certainly yes. The gooseneck spout produces a flowing stream that mimics a running faucet — which is exactly what tap-drinkers are drawn to. Most tap-drinkers switch within 24 hours. Place the fountain where your cat already goes to drink and let them find it on their own terms.

My cat already has kidney disease or has had a urinary blockage. Will this help?
- We can't make medical claims and this is not a treatment. What we can say: clean, mineral-reduced, fresh-flowing water is one of the most important factors in managing kidney stress and preventing crystal recurrence, according to veterinary consensus. The Taurine + Co Q10 supplement supports kidney and heart cell function. Talk to your vet — many specifically recommend high-flow stainless fountains for cats with kidney or urinary history.

How hard is it to clean?
- How often? Very easy. Disassembles in 30 seconds. The stainless steel components go straight in the dishwasher. Rinse the pump filter weekly. Full disassembly wash every 2–4 weeks. Because the surface is non-porous 304 stainless — bacteria and biofilm cannot grip it the way they do on plastic — it stays cleaner longer between washes.
