Gyros can be trained.

Training spiny rats, first let spiny rats get acquainted with your scent, don't be impatient. Holding the squirrel without knowing it will only make the squirrel panic.

Let spiny mice smell your fingers and hands. Put the sunflower seeds in the palm of your hand and let the spiny rat climb up to get them. Then you can try to gently touch the head of the squirrel, and then touch the body of the squirrel after it is used to it. You can then try to put the food in your hand and let the spiny mouse run over to eat it.
