I'm so sorry to hear about your loss. It must be absolutely devastating.
Regarding the dogs... all I can say is that when anyone brings dogs and cats into the same household, they are taking a risk. Your dogs did what was natural to them, as natural as barking or peeing at a tree. I can however assure you that this has absolutely NO implications on their likelihood to harm a human. Prey drive has nothing to do with human aggression WHATSOEVER. I strongly urge you to reconsider rehoming the dogs... they may like to chase small animals as the large majority of their species does, but that doesn't indicate at all that they are vicious.
