well, in my rats case, it isnt very normal...i took him to the vet about a month after i got him (i wasnt allowed to take him and got in BIG trouble *ahk*) and the vet told me he thought that frisco might have brain damage (which i sincerley doubt) but i heard about this stuff called "bach remedy" of "five flowers remedy" and im going to try it (if i can find it) and see how it goes...hopefully its not too expensive....thats why i was trying to find a food that might calm him a little, so then i wouldnt have to spend a bunch on that...oh well, thanx for ur input....
