Sure you can. It doesn't hurt to change their water every day. I usually go every couple days to dump and top off in between, but I also have 150 water bottles and that makes a bit of a difference.
I change the water daily because water that sits can grow bacteria and I am an obsessive germaphobe... The food I do every other day because that's how fast mine go through their bowls. Still, you don't want to let the water sit too much! :thumbsup:
i change it everyday...like oxchincerelyxo said...bacteria can accumulate in still water...but i only have one chin...so it's easier lol...i also change the food daily...sometimes twice daily...depending if she decided to use her container as a potty....or if there are only broken pieces left...or obviously is she eats a lot and there is not a lot left...
