Wow Chris - great news!! Two baby furkids no less. I'm sure they will be good indoor cats being so young - just ignore whatever your neighbours say!! They'll get on so well with the dog I expect most youong cats I've known have no problem with dogs - it's when they get a bit older and 'set in their ways' and if they are upset at first - they'll come round in time - don't worry.
Is the dog a great big softy? They normally adore cats.
Let us know how things progress - keeping fifngers crossed here for you.
