What are the emergency rescue methods for frozen kits (baby rabbits)?

Causes of kits freezing: one is that the due date was not recorded properly or the doe kindled early for some reason, and the kindling box was not put in place in advance; another cause is that the doe's maternal instinct is weak, and she kindled outside the box; a further cause is that after nursing, when the doe jumps out of the kindling box, individual kits that are not getting enough milk clamp onto the teat and will not let go, so they are dragged out and become frostbitten because the weather is relatively cold. Regardless of the cause, a frostbitten kit must not be left too long; if its heart is still beating, emergency measures will generally succeed.

The methods are as follows: 1. Immerse the kit in warm water (not hot to the hand, about 40°C), with the mouth and nose exposed (hold the head with your hand); once it moves or makes a sound, dry it with a dry towel and put it back in among the kits. 2. Put a hot water bottle wrapped in cloth into the straw, place a little fur on top, and lay the frozen kit on it; if it can be combined with light (generally 25-40 watts) for warmth, the effect is even better; once the kit is moving, put it back in among the kits.
