I have a mini lime tree in a pot so I can bring it indoors during winter. Are lime trees supposed to have thorns? I heard it could be a sucker plant attached to it. It grows from the same trunk and I already cut one off. The leaves look the same as the one other branch but it grows much faster and has, like I said, small thorns protruding from the base of of its leaves. Should I cut it off again or am I killing the poor thing? Please help!

Unbeknownst to many, all citrus produce thorns, so this is normal.
If it is a sucker branch, this would typically grow from around the base of the tree. This article will help you with that should thi be the cae: https://www.gardeningknowhow.com/ornamental/trees/tgen/tree-sucker-removal-and-tree-sucker-control.htm
