My kitten (approximately 1 month) has got lose motion (light green in color) and has pooped the same way twice today, it's been 5 days since we got him from a pet shop. We have been giving him normal milk and he was pooping fine until today. Yesterday i tried to put some bread crumbs in his milk, he did not have the bread but drank only the milk. Could that be the cause? Should i see take him to the Vet? I'm a little worried and this my first cat, please help
