Yea def normal... I got some that will take a F/T and not even constrict and just eat it... just so use to them already being dead... then I have others like yours that take forever to get started... my female spider will do the whole constricting thing then just stare up at me like "can i get another one please" I dunno why she thinks shes getting 2 bc ive only fed her 1 every week since i got her... Silly snakes
