I have a male and female rat set-up in a 33 gallon long tank, with pine shavings and a water bowl in the centre. Everyday I seem to have to change the waterbowl twice, because they soil their water so quickly wat can i do to stop this? Does drinking dirty water affect them in any way? How long can they drink the same water for before u have to change it?
Any help would be greatly appreciated!!!!!!
