The only pet I had was a canary, which we got when trying to get a dog 🤣
As it happens, we children were not interested in taking care of him and the little yellow bird became our father's concern (until she died).
Now in the building where we live, there is a cat (for years), who is fed by the neighbors and who lives in our entrance.
Sometimes she comes into our apartment when we come home, takes a little nap, then stretches out on our floor, we pet her a little and soon, when she gets nervous, we let her out of the apartment into the corridor of the building.
