If squirrels eat soft food for a long time, their teeth will grow too long because they can't grind their teeth. Too long teeth will hurt the inside of the mouth and affect the normal eating of squirrels. If not found in time, rats may starve to death because they can't eat anything.

So just after cutting his teeth, you can try to give him the original food and replace it with hard nuts, so that he can grind his teeth and don't have to cut his teeth again.
