It may be just me, JH, but I honestly don't think many JWs believe that the end is around the corner anymore, as their very lives bespeak. Quite a few are settled in the JW's religion, definitely with no feeling of urgency : either they routinely go about their business, being JWs out of habit, or they endeavour to get the best out of their lives, no differently from what "wordly" people do. In any instance, a supposed impending end has, IMO, no bearing in whatever decision they make in their lives. As far as adopting a pet is concerned, living in a large place, being able to take the pet along on holiday, having children, suffering from allergy or not, for example, and of course liking animals, seem to be more determining factors in the choice.
