Rabbit has red things inbetween "toes"

It's these red lines in between what you would call "Toes"

are you talking about the quick? its the blood vessel in the nails of your bunny which you should be careful not to hit when cutting their nails

If you accidentally cut it and it bleeds, just put flour or corn starch to stop the bleeding
