They kindly invited us but I said I'd need to stay with our 8 month old puppy/dog and 3 cats. I've got the diffuser, "calming" treats and some empty boxes around the house as bolt holes - anything else I can do? They are right next door, no gap. Although the dog and cats coped fine during the week with firework sounds, the noises were far away - I'm worried that this is going to freak them out totally. All tips gratefully received......
