Yes...how ARE you thawing the rodents? We don't all do it the same way...
I recommend thawing in cold water, change water a few times for larger prey -when it gets too cold to thaw quickly. Prolonged time thawing is NOT what you want...&
small prey like you're currently feeding won't take that long (maybe 30 minutes at most) just until it's soft thru-out.
Feel by hand to make sure it's thawed...only then put briefly (few minutes) in very warm water (not hot or boiling), & use a hair (blow) dryer to warm the head a bit more
right before offering but only if the snake needs it. It sounds like yours does not...maybe if the prey was a bit cooler, his response would be also? Just a thought...
In any event, rodents that fall apart easily are generally spoiled, so maybe that's also why he's not eating them? Thaw properly so they aren't spoiled, offer head-first by
tongs & see if that helps. His hyper response may also be due to hunger, if he's been refusing them, so help him out & get it right.
