I am aware that wild prey items should not be fed to captive reptiles due to potential diseases they may carry. But, would it be possible to freeze a wild caught prey item for 48+ hours to kill any parasites or diseases they may be carrying? A friend of mine has horses and catches rats daily in a live trap only to execute them with an airgun. I was thinking if I could use those rats I could put them in my CO2 chamber to dispatch them then freeze them until needed. Just seems like a lot of free food going to waste. But then again I would never feed my animals something that is potentially unsafe. Do you think any bad stuff would survive freezing? They are eating grain from horse feed after all so the gut loading is covered.
