Oh Sirrahbed you are not being neurotic. You are just feeling like this right now cause you are so far away from your babies and wish you were there with them.
Take comfort in knowing they are in good hands and will be well taken care of, no more or less than if you were right there with them.
They will be just fine. Try not to worry and enjoy the rest of your stay with your family and hug all our furbabies as if they were your own.
