If you've ever tried to take your cat's temperature, you’ll know it ends with scratches, betrayal, and a Google search that begins with, “is my cat plotting against me?”

Welcome to the age of cat health monitoring apps where your phone promises to track everything from hydration to hairballs without requiring you to wrestle a feline.

But do these apps actually help, or are they just digital fluff disguised as pet tech? I tested the top-rated free and paid cat health apps on the market, all while dodging my cat Margot’s disapproving glare.

Let’s separate the useful from the useless (and maybe even survive a vet visit in one piece).

What Should a Cat Health App Actually Do?

Unlike dogs, who will let you inspect their paws and souls with minimal resistance, cats are famously private patients. So a good app should:

• Let you log symptoms, behaviour, and diet without fuss

• Send reminders for vet visits, flea treatments, or meds

• Track weight, hydration, and litter box habits (yes, really)

• Offer real advice, not just pretty infographics

• Keep everything in one place so you’re not showing up to the vet with crumpled post-its

🥇 1. Petdiary – Best Free App for Basic Monitoring

Price: Free

iOS & Android

What it does: Petdiary lets you log your cat’s meals, medication, poop (yes, there’s a poop tracker), weight, and mood. It also gives you calendar reminders for appointments and vaccinations.

Why we liked it:

• No login or subscription needed open and go

• You can add multiple pets if you live in a fur-based democracy

• Clean, simple interface without ads screaming at you

Downsides:

• No vet integration

• No real-time health insights this one’s all manual logging

Science check: It’s not revolutionary, but the consistent tracking of behavioural changes is very helpful for early signs of illness. Vets often rely on these small shifts, especially in cats who hide symptoms.

Margot’s verdict: She stared blankly at the screen for 12 minutes. I took that as approval.

Verdict: Perfect if you want a simple, no-cost tool to keep your cat’s health history in check.

🥈 2. Petzam – Best for Virtual Vet Access

Price: Free app, £15–£30 per consult

iOS only (UK)

What it does: Petzam connects you to qualified UK vets via video call for non-emergency advice. You can log symptoms beforehand and share photos or videos of the issue—ideal if your cat hides under the bed the second a carrier appears.

Why we liked it:

• No travel trauma

• Chat history and notes are saved

• Vets were patient and didn’t sound like they were judging my flat

Downsides:

• Doesn’t offer daily tracking tools

• Not for emergencies (they’re very clear about that)

Science check: Vet telemedicine is increasingly used for minor symptoms and follow-up advice. It’s not for everything, but it’s a brilliant supplement to in-clinic care especially for anxious cats.

Margot’s verdict: She yawned mid-video call and rolled over. The vet said, “Well, at least she’s relaxed.” So, success?

Verdict: Great for on-demand, stress-free advice, but not a full health tracking solution.

🥉 3. 11pets – Best All-In-One Premium Tracker

Price: Free basic / £5.99/month premium

iOS & Android

What it does: 11pets is the gold standard for full-spectrum pet health tracking. It includes vaccine schedules, dental records, symptom tracking, feeding logs, and even hygiene notes (you can track nail trims no more overgrown claw drama).

Why we liked it:

• Works for cats, dogs, rabbits—whatever you’re parenting

• Allows photo uploads (handy for skin issues or wounds)

• You can generate a veterinary health report PDF at any time

Downsides:

• Takes a while to set up initially

• Some features locked behind paywall

Science check: 11pets is used by pet pros and foster networks, so its data model aligns with best practices in preventive care and monitoring. You can catch early signs of illness by tracking changes in appetite, behaviour, or weight things cats rarely shout about.

Margot’s verdict:She sniffed the phone. Then batted it off the table. That’s basically five stars.

Verdict: If you’re serious about your cat’s health, 11pets gives you a complete toolkit for monitoring, history, and reporting.

Honourable Mention: Tractive GPS Cat Tracker

Price: Device £44.99, subscription from £4/month

iOS & Android

Okay, not a health app per se but worth a shout. Tractive now offers a GPS collar made for cats, complete with activity tracking and location history. If your cat’s an escape artist (looking at you, Margot), it might be worth the investment.

Final Thoughts: Should You Bother With These?

If your cat is young, seemingly healthy, and emotionally opposed to everything, you might think, why bother? But here’s the thing: cats are sneaky when they’re unwell. By the time you notice something’s wrong, it can already be serious.

Apps won’t replace your vet, but they will:

• Help you spot subtle changes early

• Make vet visits more efficient

• Remind you of meds and treatments

• Prove to your cat that you are, in fact, trying your best

Whether you're a casual tracker or a spreadsheet-loving pet parent, there’s something useful (and occasionally life-saving) about putting your cat’s health in your pocket.
