How to use the pet introduction stage schedule calculator
Bringing a new animal into a home is not a single event but a staged process worked through slowly. Enter your own target days for full separation with scent swapping, meeting across a door or gate, short direct meetings and practicing shared time. The calculator lays out which dates each stage covers and the total days the plan adds up to. Any stage you want to skip takes a zero.
The math simply adds each stage target to the start date in turn. No recognized standard for how long an introduction takes was confirmed, and the answer varies widely with temperament and past experience, so this calculator does not predict a period. The dates in the table are not a forecast; they are your own target days written onto a calendar. Figures are current as of October 2026.
Stages are cleared by how both animals respond, not by a date arriving, so treat the schedule as a written plan and step back a stage if either animal skips meals or stays hidden. This calculator does not judge whether an introduction is succeeding. This tool is for reference only and does not replace veterinary care. Contact your veterinarian right away if you notice symptoms or suspect a problem.
