"Mouse before cat" 在英文中通常表示为 "to have a mouse before a cat" 或 "to put the cart before the horse"。

这个短语来源于英国民间传说，指的是在未经考虑后果的情况下做事，或者是把事情搞反了。

例句：

"You can't put the cart before the horse, you need to plan ahead before making a big decision."
(你不能把马车放在马前面，你需要提前计划才能做出重大决策。)
"Don't have a mouse before a cat, make sure you have all the information before making a call."
(不要先做决策而不考虑后果，在做决定之前确保拥有所有信息。)
