I am going out of town this weekend for a few days and am having someone come over to feed my guinea pig Snickers. Lately I have been giving him the Oasis Vitamin C drops and the multivitamin drops every other day...is it okay if he doesn't get these supplements for a few days? I syringe Snickers the vitamin C and do not want to ask my neighbor to do that because Snickers hates it and it's a hassle.
