Hi! I have three boys, Mimo, Jax, and Remy. My office is pet friendly and I would love to bring the boys to work, but would it be stressful for them if I were only to bring one of them at a time or do they need to stay together at all times? When we go to the vet, I bring all of them even if only one has an appointment. Let me know if you have any information/experience on this topic!!
