Yes, moving is a huge disruption in life and agree it is best to get settled in before adding more to your 'To Do' list. I have recently learned that the black & white cats (tuxedo cats I think they are called) are extremely affectionate. Knowing you from online, Dan, makes me think you would enjoy this type of cat as some are very aloof and distant. Any cat would be very lucky to have you but thought I would mention that one type as being a consideration.
Good luck but don't feel forced to take on more responsibility until you are ready. After our 15 year old dog died, we decided to not replace him as we had had pets practically since day one of our marriage. It would just break our hearts (again) so opted against it. Anyway, glad the worst part of moving is over for you and wish you the best in motivation vibes to getting things organized (not an easy task). :)
