I have about 22 snakes, and I do spend more time working on the rats than I do with my snakes, I would buy bulk if i had 300 bucks or betterin my bank account every couple months lol. the rats do smell, are time comsumming and at times slow breeding. but i only spend about 100 bucks a month in the taking care of them when they are able ot keep up production for me . I tried to builda rat rack only to have all but one tub chewed out ( I think I need to adjust how the tubs sits inside racks. but I going to buy a smalle chest freezer and off most the rats and work with ft more cause it is easier , plus I hate spending 5+ bucks on a rat that as big as a full grown mouse.
