Are frozen mice really that fragile?

I've been feeding my BP large frozen mice every 3-4 days(what the vet recommended) to get his weight back up after the RI shots he went through. I'm almost done with the batch I bought, but I've noticed something consistent with all the frozen feedings that's different from the usual 7-10 day small rat feeding.

When he eats frozen, he always seems to be drawing quite a bit of blood from the corpse. When he swallows them, I notice residual amounts of blood remaining within his mouth(it disappears after he swallows, so I know he's not bleeding). Sometimes the mouse is coated entirely with its own blood. Is this pretty common? Or am I making them too soft when I boil them?

the freezing process ruptures the blood vessels. When thawed out, then constricted/bit the blood will come otu easier.

Also thawing too hot and too fast will cause this as well, along with exploding guts

Delicious. Such a pleasant way of putting it... I do appreciate it, though.

Normally I just let them sit in boiling water(within a plastic bag) for 5-10 minutes until they are both warm to the touch(but not hot), smell, and are soft.

Boiling Water= YOUR PROBLEM.

Use warm water and let them sit, when water is cold, re do with more warm water. Then offer.

I wouldn't consider it a problem if the mouse bleeds, I just wanted to know why it was bleeding so easily. Unless there are other things that could go wrong by boiling frozen feeders, I've learned all I need to know for now.

Thanks. :gj:

Boiling them is just as bad as microwaving them. The rodents internal temps are far too hot, and higher chance of the rodent exploding. Its not the right way of doing it.
