A vet visit checklist for cats goes beyond a carrier and a treat — here's the play and behavioral data your vet actually needs, and how to have it ready.

Vet Visit Checklist for Cats: What to Track Before You Go

Most cat vet appointments go the same way. The vet asks how your cat has been, you say fine, you think, maybe a bit quieter lately, and then you both watch her try to dissolve into the back wall of the exam carrier. Twenty minutes later you are in the parking lot wondering if you forgot to mention the thing that might have actually mattered.

A good vet visit checklist for cats is not about remembering the carrier liner or booking the first appointment. Those are handled. It is about the behavioral data — the quiet shifts in how your cat moves, plays, and rests that accumulate over weeks and become invisible to memory by the time you are sitting in the waiting room. Your vet needs that data. They have fifteen minutes and a cat who would rather be anywhere else. You have been watching her for months. You just need somewhere to put what you have seen.

Why vets need your observations more than you think

Cats are exceptional at concealing illness. It is not stubbornness — it is evolutionary. In the wild, a cat that visibly slows down becomes prey. So by the time a cat shows a clear symptom, the underlying issue often has a head start.

This means veterinarians rely heavily on owner-reported behavioral changes to catch problems early. According to the American Association of Feline Practitioners, changes in play behavior, activity level, and social interaction are among the earliest reliable indicators of pain, illness, and cognitive decline in cats — particularly in seniors. Yet most owners describe these changes in vague terms: "she seems off," "maybe less playful," "sleeps more than she used to."

Vague is hard to act on. A dated, specific observation is a different thing entirely.

What to track in the week before the appointment

You do not need a spreadsheet. You need four things, tracked consistently for seven to ten days before the visit:

Play engagement. Is she initiating play, or does she watch the toy and walk away? Does she bat at things and then give up faster than she used to? Changes in how long your cat engages — and whether she is the one starting it — are among the clearest early signals that something is off. If you have been using CatPlay to run screen sessions, you already have this data: session length, paw-tap count, and frequency, timestamped and ready to show.
Rest and sleep patterns. All cats sleep a lot. What you are looking for is a change. Is she sleeping in different spots? More reluctant to move when you come home? Getting up from rest more slowly than she used to, or flinching slightly when she jumps down? Note what is new, even if it seems minor.
Appetite and digestion. Track not just whether she is eating, but when and how much. Has she started leaving food she used to finish? Eating slower? Approaching the bowl and walking away? Add timing: morning, evening, after play, never after play. Patterns are what your vet can use.
Vocalization. Cats vocalize for reasons. More than usual, less than usual, or a different kind — a low yowl instead of the short trill she used to greet you with — all of these are worth noting. Increased vocalization in senior cats can be an early sign of hyperthyroidism or hypertension. Absence of vocalization in a previously chatty cat can indicate pain or anxiety. Write down when you noticed the change.

The play data your vet did not know to ask for

Here is what most owners skip: structured play history. It sounds like more than it is. But if you have been running five-minute screen sessions with CatPlay, you have already been collecting it — paw-tap counts per session, how often she plays, which game types she prefers, whether engagement has shifted over time.

That shift is the useful part. A senior cat who used to bat at the laser game twenty times per session and now taps twice and walks off is showing something. A kitten who suddenly stops pouncing on prey-type stimuli when she has been obsessed with them for months is showing something too. The change is the signal. The log is what makes the change legible.

Bring a screenshot of play history to the appointment, or note the dates when you first observed the change in engagement. "She stopped engaging with screen play around March 10th" is actionable. "She's been less playful lately" is not.

Signs of pain that hide in play behavior

Cats in pain often show it most clearly when playing — or rather, when they stop. A few patterns worth knowing:

Stopping mid-play and sitting very still. Cats sometimes pause to observe. But if she stops play and immediately adopts a hunched posture or shifts her weight, that is worth noting.
Reluctance to jump during play. If she used to leap onto the couch to follow a toy and now stays on the floor, that is a mobility signal — often an early sign of joint pain or arthritis, especially in cats over seven.
Batting without pouncing. Full predatory sequences involve approach, bat, crouch, pounce. If only the batting is happening — no crouching, no pounce — the crouch may hurt.
Shorter sessions initiated by the cat. The cat who used to sprint and tumble for eight minutes and now taps twice and retreats to her bed is not bored. Bored cats often redirect to something else. A cat who retreats may be managing something.

These are observations, not diagnoses. But your vet can use them to decide what to examine more closely.

The five questions worth writing down the night before

The end of a vet appointment is when your prepared questions evaporate. The exam went fine, the carrier is already back in the car, and the receptionist is making the next appointment. Write these down the evening before:

Is this behavior change something I should be tracking more systematically between now and the next visit?
At what age does this change from normal slowing-down to something worth investigating?
Are there environmental adjustments — different play frequency, lower jump heights, feeding changes — that would help?
What specifically should I be watching for that would mean coming in sooner?
Is there a blood panel or additional screen that makes sense given her age and what I have described?

That last question catches more than people expect. Routine senior bloodwork often finds things that behavioral observation alone cannot. But your behavioral notes give the vet context for interpreting the results.

In closing

A vet visit checklist for cats is not a one-time form. It is the habit of watching your cat with enough structure to describe what you see to someone else. The owners who can say "she went from twelve paw-taps per session to two, and it started around March 15th" give their vets something to work with. The owners who say "she just seems quieter" give them a puzzle with no edge pieces.

Your cat cannot tell the vet anything. You are the only historian she has.
