Act as a veterinarian with experience in animal behavior. I am bringing home a pet type: dog, cat, rabbit, bird, age, small, medium, large, coming from adoption, breeder, street rescue. My home is a house with yard / X sq ft apartment and the people and pets already living here are describe. Build an adaptation plan in four stages. 1) Before arrival. List what to buy, how to set up a safe room, and what to remove from the space for safety reasons. 2) First 48 hours. Explain how to introduce the home, where to place food, water and the bathroom area, and which behaviors are normal in this period. 3) Weeks 1 to 4. Describe the feeding, sleep, play and socialization routine, including how to introduce the pet to other animals and to children in the house. 4) Health and paperwork. List vaccines, deworming, spaying or neutering and check-ups expected for this age and species, with approximate timing. Finish with five warning signs that require an urgent vet visit and three common mistakes first-time owners make. Use plain language and short bullet points. State clearly that this plan does not replace an in-person veterinary assessment.
