I had the impression so far that pets are at all more a thing for I-types in general. I never wanted a pet but I came in touch with them quite early in life, since my ISFJ mom liked them. Our family had a budgie when I was young and I liked him. You could stand with him on the balcony and he would be sitting on your shoulder not flieing away. Quite amazing nice little pet. After the budgie we had guinea pigs. They were cute and fluffy but far too shy to be ever taken out of the cage. We let them stroll thru the garden mowing the turf that was quite funny, but guine pigs werent really my thing.
Now with my girlfriend we have a cat. My girlfriend grew up in a more rural area and she had two cats, two turtles, a lot of rabbits, guinea pigs, hamsters, so a lot of animals already. She's INFP and always talked to me about how gladly she would like to have a cat again. So I went out that one day and bought a male cat, british short hair, color creme. A very beautiful cat with a good character, very stress-resistent so really good for kids. I like that cat too since it bonds me and my gf but I can safely say if I should ever part with my gf for some reason I hope never happens, I wont buy an animal on my own again.
An automated spider-beer-automaton that can open the fridge and bring you a new beer, that would be a goal
