Hi so both of my cats are now pooping darker, black looking stools. The shape seems to be the same from their healthy brown poop. This has been happening for about a week now after I transitioned them from kitten food to adult food. They are both 11 months old. When I noticed the change in color, I thought it must just be because of their change in diet...but after looking up possible reasons and finding all of them to be harmful, I'm worried and am wondering if this is at all typical after transitioning foods. For specificity, I switched from wet Purina Fancy Feast kitten food to Weruva wet classic cat food. Any advice would be appreciated! Thanks!
