Is my aging cat's change in behavior normal or a vet emergency?
Hello. If he is eating & acting OK, you can probably hold off rushing Mojo in to your vet, but if he has another period of not eating, lethargy, or he just seems more off to you, don't wait. Recheck that bloodwork. If everything is normal, then it is OK to wait a year for follow-up bloodwork, but things can change pretty quickly as pets age, so it is not abnormal to monitor bloodwork every 3-6 months, depending on any extenuating circumstances. So, follow your instincts. No cat likes to go to the vet, but if you are concerned, it is always best to make sure things are OK sooner than waiting months for the next visit.
