Or it is just only about the weight? The miracle ~1000g? How much should two year old bally weight?

My baby (don't know the gender) stopped eating in August 2019. Before it s/he ate without problems; mouses and rats, it loved everything. But then a sudden wild August came.

Rats? They were big NO. Mouses? Hmmm... Maybe one 30g mouse in December and 30g x 4 in March. Otherwise? No. Everything is a big no-no. No matter how bloody, small or warm the prey is... Nope. It just sniffs and leaves. I have had him for 1,5 years now, and we had no problems before this. So I don't understand what happened.

A terrarium is the same, no changes, sheds are 100% success everytime, and it appears to be healthy, no mites, "flu" or lethargy. Even now it is decorating the terrarium and running around it, looking for food. It stays hidden during the day. I don't handle it often, maybe once in a month when I weight it.

So it got me thinking, did it hit the Wall back then? Is it even a real thing? It was ~850g in September, and now it is 1030g so.. "the wall"? What do you think?

And more importantly, if it is the mysterious wall; how to get over it?!

I know I should now keep on weighing it, keeping an eye on it in case of weight loss or illness, but..., I'm just worried. Damn these picky eaters. Oh and sorry about messy writing and poor grammar, it is 1 am here, and I'm not good in English anyway. Thanks for your answers!
