We make the checkup happen at home: sand that keeps urine on top, a pole that catches it mid-walk, and strips that read the answer in two minutes.
Pick the patient — we'll bring the right room to them.
We turn routine "pee time" into a painless, two-minute wellness screen — catching early signs of diabetes, kidney disease and UTIs before they become expensive emergencies. Our patented hydrophobic sand collects clean feline samples without needles or stress, our telescopic P-Pole does the same for dogs mid-walk, and our CheckUp strips read the answer on the spot. At a fraction of a clinic urinalysis, we keep pets healthier — and their humans' wallets calmer.
Five ways in — matched to the question you're asking.
| Solution | Best for | What it checks | How it works | How fast |
|---|---|---|---|---|
| Hydrophobic Sand Kit | Cats — vet drop-off | Collection only | Urine stays on top of the sand; pipette to vial | One morning |
| CheckUp Cat Kit | Cats — first checkup | Glucose, pH, blood, protein | Sand collection + included strips | ≈ 60 seconds a read |
| CheckUp Pro | Cats & dogs on a watch-list | Full 10-parameter panel | Collection + Pro strips | ≈ 2 minutes |
| Testing Strips | Refills & routines | Protein, glucose, blood or all ten | Dip in any clean-caught sample | ≈ 60 seconds |
| Health Indicator Litter | Between checkups | pH drift & blood, visually | Crystals change color at each visit | Every scoop |
Monitoring support, not a diagnosis — a flagged result goes to your veterinarian with the reading in hand.
Sand for cats, P-Pole for dogs — a clean sample with zero needles and zero drama.
Dip a CheckUp strip and read it against the chart — about two minutes, at the kitchen counter.
Log the result, retest on schedule, and hand your vet a trend instead of a guess.
Easy-to-use kits for stress-free collection and testing, right from the comfort of home.

A smarter litter box check
Our indicator litter changes color the moment it meets your cat's urine — flagging potential urinary issues early, at every single visit, with no sampling at all.
Fourteen years old, hates the carrier like it owes her money. Poured the sand at 7am, had a vial in the fridge by 9, results from the vet by Friday — kidney numbers caught early enough to matter. I cried in the parking lot, honestly.
The strip turned the glucose pad dark on a Tuesday. Vet confirmed diabetes on Thursday and said the early catch made the treatment plan easy. A twenty dollar box did that.
I am 34 weeks pregnant and cannot be near a soup ladle situation. The pole extends, the cup clicks off, my dignity survives the entire walk. Whoever engineered this has caught urine before.
Our UTI-prone void goes through phases, and the indicator litter is our tripwire — it went blue-green on a Sunday, strips confirmed Monday, antibiotics Tuesday. Shortest UTI arc we've ever had.
Diabetic senior beagle. The ten-parameter tube lives next to his insulin, and the weekly strip photo goes straight to our vet's portal. She calls it the best homework any of her clients turn in.
Bought the UTI bundle at 11pm during a straining episode, tested the next evening, walked into the clinic with a photographed strip. The vet skipped a whole appointment of guessing. Worth every cent.
The coating is genuinely hydrophobic: liquid cannot soak between the grains, so it beads and pools on the surface. Burying just puts dry sand over a liquid bead — sweep the sand aside and the pooled sample pops back up whole. That physics is the patent.
Most do without ceremony, because it is 100% natural sand — no perfume, no crystals, no chemical smell. Picky cats may circle it for a few hours first; give them a clean, dry box, no alternative litter available, and a day of patience. A refusal after that is rare enough that we wrote a returns page about it.
No, and we will keep saying so. Strips are an early-warning system: they tell you something is worth a professional look days or weeks before symptoms would. One mild abnormal on a healthy-acting pet means retest in 48 hours; a repeat abnormal, any strong positive, or any reading plus symptoms means a same-week vet visit — with your readings in hand.
Strips want a sample under an hour old at room temperature. For a vet drop-off, refrigerate the capped vial and deliver it the same day — urine chemistry starts fiction-writing after about 24 hours even when cold.
For a cat: the CheckUp kit — sand plus the four-indicator strips covers the questions vets ask first. For a dog: the CheckUp dog kit with the pole. Go Pro (ten parameters) when there is a specific watch-list: a senior, a diabetic, a kidney or UTI history.
Because a urinalysis wants one clean, uncontaminated collection — and sand is heavy, so we portion exactly what one collection needs to keep the box affordable to ship. All three bags go in at once, the depth feels normal underfoot, and the box does one job perfectly rather than three jobs badly.

Read in the waiting room →At KIT4CAT we make at-home urine collection and wellness testing for cats and dogs — the unglamorous, genuinely useful corner of pet care. Our patented hydrophobic cat litter is natural sand with a coating that keeps cat urine on top of the surface, turning urine sample collection from a clinic procedure into a morning at home: no cystocentesis needle, no carrier panic, just a pipette, a vial and a calm cat. For dogs, our telescopic CheckUp P-Pole catches a mid-walk sample without the crouch.
The testing half of our shelf is the CheckUp strip family: single-parameter urine test strips for protein, glucose and blood in urine, and the full 10-parameter panel reading pH, ketones, bilirubin, urobilinogen, specific gravity, nitrite and leukocytes. Every strip reads in about two minutes against a printed chart, and every result is built to be photographed and handed to your veterinarian — we are the early-warning system for UTIs, kidney disease and diabetes watch, never a replacement for the clinic.
Between checkups, our color-changing health indicator cat litter monitors every visit to the box on its own, flagging pH drift and traces of blood in urine at a glance. And when the question is already known, our sample-and-test bundles pack collection gear with the right strips — glucose watch, UTI suspicion, or the complete panel — into one box for cats and dogs alike.
Everything we make checks out at our official storefront, ships portioned to stay affordable, and comes with the same standing advice: test on a schedule, write results down, and bring your vet a trend instead of a guess. Early is cheap. Late is not. That arithmetic is why we exist.
Simple, trustworthy tools to support your pet every day — every kit one click from your door, one quiet morning from an answer.
