So my cat has E.coli. She is on a form of Amoxi, so I kow she will be fine. But I want to know how she contracted it. The litter box is scooped daily and cleaned once a week with a scrub down and new litter. And I am a vegetarian, so no uncooked meat at this house. She only eats wet GD food. So, I don't know how she got it and the other cat is fine with no illness. Any ideas? I want to prevent this in the future. Thanks!
