Act as a veterinarian and animal behavior specialist. I am about to adopt a pet and I want to find out which species and size actually fit my life before I decide. My context: I live in a house or apartment of size, with number people, including children or elderly, if any. I am away from home hours per day. My monthly budget for a pet is amount and I have little or a lot of experience with animals. Constraints: allergies, building rules, other pets. Follow these steps: 1) Suggest three compatible options with species, size and energy level, explaining why each one fits. 2) For each option, estimate the monthly cost and the first year cost, splitting food, vaccines, spay or neuter, grooming and unexpected vet bills. 3) List the daily time required for walks, play and cleaning. 4) Point out where my routine could become a problem and how to work around it. 5) Close with one recommendation and the questions I should ask the shelter or breeder. Show steps 1 to 3 in a comparison table. Base everything on responsible ownership and tell me plainly when the best answer is to wait.
