Where I grew up I don't remember many JWs having pets and very few elders had any pets. In contrast we always had cats and growing up I remember 2 dogs as well...along with a tortoise, rabbits, guinea pigs, parakeets, hamsters and rats (at various times). I think my mother had a duck at one time but that may have been before she became a JW and certainly before I was born.
I do recall one circuit
serpent servant overseer having a real issue with pets. He hated that some treated their pets like little children. He went as far as to say that the Bible says nothing about cats (incorrectly as the Bible mentions big cats) and that dogs are always mentioned in a negative way. The time caring for pets takes away from field service, meeting attendance and assemblies and blah, blah, blah. And in the new system (tm) we'd have all the time in the world for pets. I guess a lot agreed.
I didn't have any pets for a long time as I liked to be able to travel away from home and not have to worry about getting pets looked after.
We have a cat now.
