If your cat is sick, injured, or just “not acting right” and you’re not sure how urgent it is, please call us during business hours. The sooner we hear from you, the better we can help guide you to the right level of care — whether that’s a same-day urgent care visit with us, a scheduled appointment, or a referral to an emergency hospital.
