Hey everyone, I'll be leaving my 2 sibling cats (male and female)who are almost a year old, for about 3 weeks. My cousin and his wife will be house sitting for me and taking care of them while I'm gone. The cats are not really used to people...when I have visitors they hide for hours, nowhere to be found....even after the people are gone. I won't be going away for another 2 1/2 months, but I am worried of how they will cope with my cousin.
