How do I know if my cat is anxious or just being a cat?

Anxiety shows as a *change* in baseline behavior — a normally social cat hiding more, a normally tidy cat missing the litter box, increased grooming to the point of bald spots, or new aggression. Aloofness and napping are normal cat behaviors. Sudden behavioral shifts are not.

Can cats have separation anxiety?

Yes — though it's less common than in dogs and frequently missed. Signs include excessive vocalization when you leave, eliminating outside the litter box only when alone, destructive scratching during your absence, or refusing food until you return. Indoor-only single cats are most at risk.

Will Feliway actually help my anxious cat?

Feliway Classic and Feliway Optimum (a stronger formulation released in recent years) have the most peer-reviewed evidence of any over-the-counter cat calming product. Effects are modest but real — best for territorial stress, multi-cat tension, and travel. Plug it in 24/7 in the cat's main living area for at least 30 days before evaluating.

When should I take my anxious cat to the vet?

Always rule out medical causes first. Sudden anxiety in a previously calm cat can signal pain, hyperthyroidism, urinary tract disease, or cognitive decline in seniors. Behavioral medication (fluoxetine, gabapentin) is also more accessible than most owners realize and often life-changing for chronic cases.

12 Signs Your Cat Has Anxiety (And What to Do About It)

Cats are evolutionary masters of hiding distress. In the wild, showing weakness invites predators — so a stressed cat looks normal until the signs are obvious enough that something is already wrong. By the time most owners suspect anxiety, the cat has been struggling for weeks or months.

This is the checklist veterinary behaviorists actually use. If three or more apply, your cat is anxious — and there's a lot you can do about it.

The 12 Signs (In Order of How Often They're Missed)

1. Over-grooming to the point of bald spots

"Psychogenic alopecia" is one of the most under-recognized signs of feline anxiety. Look for thinning fur on the belly, inner thighs, or front legs — areas the cat can easily reach. Distinct from allergies because there's no skin lesion underneath.

2. Litter box avoidance

A cat that suddenly pees on a rug, bed, or laundry pile is not "being spiteful" — that behavior doesn't exist in cats. They're either marking due to stress, avoiding a box that feels unsafe, or signaling pain. Always rule out a UTI first.

3. Hiding more than usual

A cat that suddenly disappears for hours, sleeps in unusual spots, or stops greeting you is communicating discomfort. Especially significant if a previously social cat goes quiet.

4. Reduced or refused food

Stressed cats often skip meals. A 24-hour food refusal in a cat is a veterinary emergency — feline hepatic lipidosis can develop within 48–72 hours of fasting, especially in overweight cats.

5. New aggression

Toward humans, other pets, or specific family members. Often misread as "the cat hates them" — usually the cat is overstimulated or feels cornered.

6. Excessive vocalization

Increased meowing, yowling at night, or vocalizing in unusual patterns. Most common in older cats but can appear at any age with stress.

7. Hyper-vigilance

Ears constantly swiveling, dilated pupils in normal lighting, startling at small sounds, tail flicking at rest. The body language of a cat that doesn't feel safe.

8. Compulsive behaviors

Repetitive paw chewing, tail chasing, wool-sucking, pica (eating non-food items). All are stress-driven self-soothing behaviors that can become entrenched.

9. Changes in sleep patterns

Sleeping much more, sleeping in odd locations, or unable to settle. Cats normally sleep 12–16 hours/day in predictable patterns. Disruption matters.

10. Excessive scratching of furniture (suddenly)

Sudden uptick in scratching, especially at boundaries (windows, doors), is often territorial stress — usually triggered by an outdoor cat the owner hasn't noticed.

11. Changes in interaction

Avoiding being picked up when they used to enjoy it. Nipping during petting they previously tolerated. Refusing to engage with toys they liked.

12. Physical symptoms

Frequent vomiting (with no dietary change), constipation, intermittent diarrhea, or recurring URIs. Stress suppresses feline immune function — physical symptoms often track behavioral ones.

Common Triggers Owners Don't Realize Are Triggers

A new pet in the home — even one that seems "fine"
A new baby, partner, or roommate — schedule and scent disruption
Outdoor cats visible through windows — territorial stress with no resolution
Moved furniture or rearranged litter boxes — cats are sensitive to environmental change
A new neighbor's pet — even one your cat never sees
Construction noise, even brief
Owner stress — cats mirror human cortisol patterns measurably
Loss of another pet — surviving cats often grieve
Inconsistent feeding schedule — security comes from predictability
Multi-cat households without enough resources — fewer than N+1 boxes, water bowls, and resting spots

Step 1: Rule Out Medical First

A vet visit should always come before assuming behavior is purely psychological. Common medical causes of "anxiety":

Urinary tract disease (especially FIC — feline idiopathic cystitis, which is itself stress-driven)
Hyperthyroidism (older cats)
Arthritis pain (silent in cats; causes hiding and avoidance)
Dental disease
Cognitive dysfunction in seniors

Bloodwork, urinalysis, and a full physical should be the first investment.

Step 2: Fix the Environment Before Trying Products

Most "anxious cats" are responding to a fixable environment. Audit:

Resources: N+1 of everything — litter boxes, water, food bowls, scratching posts, beds. For 2 cats: 3 of each.
Vertical territory: cat trees, shelves, window perches. Cats feel safer high up.
Hiding spots: at least 2–3 per cat. Boxes, covered beds, igloos.
Window views: allow watching outdoors unless an outdoor cat is the trigger — then block sightlines.
Litter box quality: unscented, fine-grained clumping, large box, scooped daily.
Predictable routine: feeding, play, and quiet time at consistent times daily.

These changes alone resolve a surprising percentage of "anxiety" cases.

Step 3: Add Calming Aids

In order of evidence strength:

Tier 1 — Best evidence

Feliway Classic / Feliway Optimum diffuser — synthetic facial pheromone. The strongest OTC option for territorial and generalized cat stress.
Feliway MultiCat — different pheromone, specifically for inter-cat tension.
Zylkene (alpha-casozepine) — milk protein derivative, well-tolerated, modest but real effect.

Tier 2 — Moderate evidence

Solliquin — L-theanine + magnolia + phellodendron blend
Composure (VetriScience) — situational use
Calming music ("Through a Cat's Ear")

Tier 3 — Weak evidence

Most pet-store calming chews
Lavender or chamomile sprays
Bach Rescue Remedy

Step 4: Talk to Your Vet About Medication

This is no longer a last resort. For cats with chronic anxiety affecting quality of life, medication often makes the rest of the plan possible:

Fluoxetine (Prozac) — daily SSRI, well-studied in cats, takes 4–6 weeks
Gabapentin — common for vet-visit anxiety and travel; sometimes daily for chronic stress
Trazodone — situational, pre-event
Clomipramine — older but still useful, especially for compulsive behaviors

The American College of Veterinary Behaviorists (ACVB) and IAABC list cat-specialized professionals.

What Owners Get Wrong

Treating it as a phase. Cats don't "grow out of" anxiety — they entrench coping behaviors that get harder to reverse over time.
Punishing symptoms. Yelling at a cat for peeing outside the box adds stress to the trigger.
Adding another cat to "give them company." Sometimes works. More often makes it worse.
Trying one calming product for three days. Most aids need 2–4 weeks to evaluate.
Skipping the vet. Behavior is the visible part — pain and disease are what's underneath.

The Takeaway

Cats hide anxiety by design, which means most cases are caught late. If you've spotted three or more signs from the list, you're already ahead of most owners. The path forward is medical workup → environmental audit → calming aids → behavior medication if needed. Most cats improve dramatically when the right combination is found.
