I just got a kitten and she is 7 weeks old and has no shots yet - she just caught a mouse…

Even little kittens can be stealth hunters! Your kitten will likely be fine just be sure and mention this to your veterinarian. The vaccines she will get protect against cat diseases and not anything transmissible from the mouse.

She could pick up parasites from the mouse however, so your veterinarian may elect to give her a deworming medication. Congrats on your new little huntress!
