Veterinarian Founded

Dr Bolu Eso is a veterinary surgeon, broadcaster, and co-founder of Kitty Sense, With over 7 years in clinical practice and a regular presence across TV and media, he's become a trusted voice on animal health. But it was what he kept seeing in the clinic, cats arriving too late, owners unaware anything was wrong, that led him to act. Cats are experts at hiding discomfort. By the time symptoms are visible, the problem has often progressed. Our very first product Litter Sense exists to change that: giving every cat owner a simple, daily way to stay one step ahead, no vet visit required.

What our customers say

Verified customer

I’ve got an older cat and I’m always worrying I’ll miss something. This makes me feel like I’m not just guessing anymore. The litter actually changes colour and it’s very obvious when it does. No dust, no strong smells, and my cat didn’t avoid the tray at all which was my biggest worry.

I took photos of the colour change to my vet as my cat’s wee went blue, I uploaded a picture, she said it was actually really useful. I took her in for a check up and it turned out she had a mild UTI. The vet was impressed. Honestly think every cat owner should be using this. Really chuffed with it.

Cat adjusted fast, I was worried she wouldn’t use it. Took maybe a day? No issues since. No smell either.
