Wintering animals is a difficult thing to do but when you live close to his natural habitat you can just move his home outside in a rather protected space and then also change up some of his terrarium to make it more wintering friendly.

You should really post a picture of the toad and the terrarium you are keeping him in.

Reptilians and amphibians have many special needs like uv light. Temperature gradients. Basking spots. Special nutrition and more so its highly likely your toad is missing something and if you dont change that it will prolly never produce any venom.

And also guys. Could you just stop with the hate? The toad is at his place. And he will prolly not be able to release it in its natural habitat. Also releasing it would probably kill it in less than a month. You cant just release animals especially not if this one was captive bred. Also releasing an animal is hard because you first need to find their actual habitat. Just releasing it in the same reagion is not enough. You need to find a population and then slowly train it back to be self sustained.

Its true that some animals should not be kept. But a toad is not one of those animals. Toads rarely travel long distances and are pretty happy with food water and shelter.

You are acting like a toad is a horse who needs big plains to migrate. A toad will prolly never even fully use the pond he is living in. A corner is enough. And most movement only happens because of food search.

You should rather help to make the life of the toad better instead of just spamming shit into this thread that doesnt add to the discussion and only makes you seem like very superficial internet group bullies.
