You evidently dont know the amount of work it takes to keep and care for several hundred rats. The truth is frozen is easier amd more convenient to the keeper.
Before I got rid of my rats, my snakes ate weekly and almost never missed a meal. About a year ago I decided I wanted my personal time back on the weekends. ***YES I spent most of the weekends cleaning tubs and racks. Not to mention the twice a day checking on them for food, water and dirty tubs.*** Since the trying to switch, I have taken time off of breeding them because they are hit and miss on feeding on f/t. The big girls are not putting on weight as fast.
Due to all of this I have been contemplating downsizing my collection.
I removed the stress of the rodents from my life and now the snakes are almost as much of a stress getting them to eat on some type of regular schedule.
I have always told people to feed them what they will eat and almost feel like a hypocrite now......
In my case switching to frozen has taken the fun out of the breeding hobby for me.
