I have four rats Who have always been really easily handled. Today I went to pick up one of the rats and he started squeaking uncontrollably and became very tense and jumped out of my hands. He is always extra squeaky more than the others but I've never had an issue with him being scared of me picking him up. You would think an injury but other than me picking him up he is acting normally. He seems terrified for some reason. Anyone have any ideas on what the next step should be or what's going on. The only thing out of the norm was a pretty bad thunder and lightning storm last nite.
