Swallowed substrate.

[Sauzo]

I do as well, I never thaw in water or with water. I leave my rodents to thaw for hours. The reason I had substrate stick this time was because one rat (that i saw) exploded when constricted (I think because I thawed for 8hrs) and the blood caused the substrate to stick. I'm assuming the same happened with the boa although I didn't see it. Both are feeding on the same sized rat so it makes sense 8hr thaw might be too much for weaned rats to thaw, both had the same substrate issue. The JCP takes rat fuzzies but as I said she refused to eat today. My WLP takes a medium but I imagine since its bigger the 8hr thaw wasn't enough to cause the blood to settle on one side, and if it is it didn't explode since the WLP will not constrict, he just takes the rat once I leave the room.

Just make sure you are fully thawing the stuff. Smaller rats isn't that big of deal as you can easily tell if they are fully thawed but for big stuff, you want to make sure the insides are thawed and not frozen still. That's why I use warm water. Easier to tell if 2XL guinea pigs and large rats are fully thawed as I just kind of squeeze them a little and you can easily tell as you will feel a big temp difference.
