Spay & Neuter Timing Quiz (Dogs & Cats)

A pet-parent-friendly quiz to help you decide whether to wait, schedule now, or talk to your vet first.

For dogs, timing is often based on expected adult size. For cats, the ideal window is typically 4–6 months because kittens mature early.

This quiz is educational — always confirm timing with your veterinarian, especially for adult or senior pets.

About this quiz

Not sure if you should wait or schedule? This guide explains how we think about timing.

Sniffaloo’s spay/neuter quiz gives you a vet-informed starting point for choosing the best timing for your pet. It’s based on widely used veterinary guidance: size-based timing for dogs (small, medium, large/giant) and an early timing window for cats (typically 4–6 months).

Your result explains why the quiz recommends waiting, scheduling now, or talking to your vet first—especially for adult and senior pets, where the decision depends more on overall health and anesthesia planning than growth milestones.

What this quiz considers

  • Pet type (dog or cat)
  • Sex (male or female)
  • Age (in months)
  • Expected adult size (dogs only)
  • Higher pregnancy/breeding risk from contact with intact pets

What this quiz does not do

  • It does not diagnose medical conditions.
  • It does not replace a veterinary exam or pre-surgical screening.
  • It can’t account for breed-specific risk factors or individual health history.

Quick FAQs

Is it ever “too late” to spay or neuter?

Usually, no. Adult and senior pets can still benefit, but your vet may recommend bloodwork and additional screening to plan anesthesia safely.

Will spaying or neutering change my pet’s personality?

Your pet’s personality stays the same. What may decrease are hormone-driven behaviors like roaming, calling, or marking. Training and enrichment still matter.

Why is cat timing earlier than dog timing?

Cats can reach sexual maturity early, and delaying increases the risk of pregnancy, roaming, fighting, and stress behaviors. Cats don’t benefit from delaying surgery for joint development the way some large-breed dogs may.

What should I ask my vet before surgery?

Ask about pre-anesthetic bloodwork, pain control, recovery steps, activity restriction, and what signs should prompt a recheck (swelling, discharge, lethargy, poor appetite).
