Like Craig about 6 or 7 years ago I had some pet rats (scratch and sniff) that I was unable to take care of due to substance abuse. I made the decision to go to treatment and had to do something with my pets. I decided to put them up for adoption and made a craigslist ad. The benefit to this was the ability to screen potential future owners, check in their knowledge of keeping rats etc. I was able to find someone who had a wealth of knowledge and I felt 100% comfortable with the rats’ new home. If you are unable to care for the animals and give them the attention they need/deserve rehoming them is the responsible thing to do. It was hard to let my animals go but I continued to remind myself of the benefits. The rats would get more regular cage cleanings, more human interaction/ bonding time. Sometimes the best decision is the hardest. Good luck with whatever you decide to do.
