Don’t freak out – it happens often to shelter animals given the amount of stress they are under. Often they come from the shelter with something called stress colitis and it causes them to suffer bouts of diarrhea tinged with blood on occasion. If you see this, call your vet to discuss. Depending on the severity, they may have you come in for an exam, OR they may have you watch it for a day or two, particularly if your new pet is acting otherwise normal (eating, drinking, playing) to see if it corrects itself, which it often does. Again, if you are one of our Fosters, please call us if you notice anything like this so we can assess next steps with you and your vet if needed.
