We will be going out of town for 5 days. Our cat normally gets her insulin at 9 a.m. and 9 p.m. Our son will be sitting with our animals but he must leave for work at 6:30 a.m. and will be gone until about 6:00 p.m. Can I change Beeber's insulin schedule for those 5 days, and if so, how should I go about the change?
