20 Things You Somehow Missed In The Mummy (1999)
5. Where Did the Cat Come From?
After Rick encounters Imhotep, he's surprised when the reborn immortal flees in terror after seeing a cat. As a result, Rick has a cat primed and ready the next time Imhotep rears his ugly head, compelling the high priest to run away once again.
Now, some people have pointed out a minor plothole surrounding that cat. If Imhotep is afraid of felines, Rick should have one with him at all times to keep the demonic mummy away. However, Terence Bay explains how Imhotep will only fear cats until he's fully regenerated, which occurs soon after.
But there's another inconsistency surrounding our four-legged friend. When Rick enters the room to confront Imhotep, his hands are empty. In the next shot, Rick is inexplicably holding a cat. After the tabby defiantly hisses at Imhotep, it disappears in the next shot.
Due to the kitty's vanishing act, it seems like Imhotep isn't the only one with magical powers.
