Frequently Asked Questions
When should I spay or neuter my cat?
Most veterinarians recommend spaying/neutering at 4-6 months of age, before the first heat cycle. Some shelters and clinics perform the procedure as early as 8-12 weeks (pediatric spay/neuter), which is safe and allows early adoption.
Will my cat's personality change after spay/neuter?
Behavioral improvements include reduced spraying (90% of males stop), less roaming and fighting, reduced yowling (females in heat), and decreased aggression. Their core personality stays the same — they'll still be playful and affectionate.
