Cats hide pain.

This fall, Zorro started losing weight. Then came the vet visits, the bloodwork, and a lot of three a.m. searching. Every answer online said something different. We wanted one place with real answers, and the sources behind them. So we built it.

Six chapters. Stress, and the multi-cat home. Teeth, and the pain cats hide. The litter box, and the one sign that means emergency vet, right now. Food and weight. Heat, spaying and neutering. And kittens, from the very first hour.

Sixty-plus short lessons. Every health claim cited to its veterinary source. Printable checklists. And an emergency card for the fridge.

From Zorro, Dina and MJ, to you. The F.B.I. Field Guide. Feline Body and Instincts. Get it below.

Zorro

Chapter 1: Psychological

A cat that hides, licks itself bald, picks fights or yowls at three in the morning is telling you something, and the first job is to work out whether that something is in its head or in its body.

Chapter 3: Urinary and litter

When a cat starts peeing outside the box, the box is only half the story; the other half is a bladder that may hurt.

Chapter 4: Nutrition and weight

Food is the one decision you make for your cat every single day, and it is where most of the slow, preventable problems start.

Chapter 3 · Urethral obstruction in males

Call your vet

Emergency, go now

A male cat straining to urinate and producing nothing, or only drops: this is the picture of urethral obstruction, which occurs almost exclusively in males and is life-threatening.³¹⁴²⁸
Repeated trips to the box with nothing coming out, with or without crying: unproductive straining is the most frequent presenting sign of a blockage.³
A cat straining that you think is constipated: owners commonly mistake a blocked cat for constipation, and that mistake costs the hours that matter.³²⁸
Straining plus vomiting, not eating, lethargy, hiding or weakness: once a blockage has lasted beyond about a day the cat becomes systemically ill, and these are the signs of that.³
A cat found collapsed, cold, or breathing oddly, with any history of straining: severe prolonged obstruction presents collapsed, with a slow heart rate, low body temperature and shock.³²⁸
A hard, tense, painful belly in a cat that has been straining: a distended painful bladder is the examination finding of a blockage.³²⁸
Any cat that has not passed urine in 24 hours: waste products build up, potassium rises, and the sources put uraemia at 24 to 48 hours and death within roughly 24 to 72 hours of complete obstruction.³¹⁴²⁸

The emergency card at the start of the course has every one in one place.

The cast

Meet the faculty.

Written by their humans, Robin and Younos.

3 cats · 1 brand

The dad · Orange tabby
Zorro
Dramatic, chronically online, entirely convinced he runs the household. The one people show up for.
The mom · Tabby
Dina
Sleek, fast and unimpressed. The straight face every good bit needs.
The daughter · Fluffy white
MJ
Soft, floppy, chaos in slow motion. If Zorro is the hook, MJ is the payoff.

Questions

Good to know.

Anything else, write to hello@robinugc.com.

No. It is education, not veterinary advice. It helps you notice sooner and ask better questions. If your cat is in distress, call your vet or an emergency clinic now.
