Have you listed your place yet? Hopefully the dog won't be around when you have showings, or that could be a potential turnoff for a buyer.
I don't know whether it is too late and you probably might have done it, but would it be beneficial to check on the neighbors over weekdays/weekend to see how everyone get along? It will be kinda annoying if neighbors are blasting music every weekend or letting their animals roaming around biting people.
If you do see that cat barking, you might be able to make some money off of it!
