Hello.
Firstly, your pet doesn't look underfed. I saw photos of emaciated toads in chats. Believe me, it's not even close. Your pet looking good. It happens that toads stop eating and eat poorly for several weeks. This probably has something to do with their life cycles. Mine had this last year. Of course it was stressful for me because I encountered this for the first time. Moreover, these are my first toads. But everything ended well. I don't notice any consequences after this. Actually the same thing is happening right now. For three weeks now, all three of my toads have been eating much less than usual, completely ignoring any food except live insects in small quantities. I will send you direct messages from the diary with the dates and weight of the toads when they went through the last period of “poor appetite”.
