No I wouldn't My sister comes over everyday that we are gone spends time with them feeds them as they normally would be fed plays with them. But my cats are VERY VERY social and needy!
I also go to my sisters if they are out of town and do the same thing I go at least once a day but she comes here twice a day. Mine are way more needy than hers are. I can sit there and try to play with hers and they walk away from me

while mine will jump up on her and snuggle

But even if they were not as social I would want someone to come by and check on them at least once a day just for my own peace of mind and to know that their scheduel was not messed up.
