my cat kills and eats rats very often, since she’s a farm kitty. she also drinks from my cup while i’m not looking. a bout a month ago i started getting hives with no apparent cause. they just, showed up. i’m not allergic to anything, and at the time i haven’t done anything different than usual, so i know they weren’t an allergic reaction of any kind. a few weeks after, i still had the hives, but now i have inceased appetite and restlessness. could my cat have a parasite that she got from a rat, and then transmitted it to me by contaminating my water?
