I've seen cashmere Christmas trees but it seems it's just the tips that are cashmere and the rest is the plastic/pvc branches that they love to chew on and eat.
Had to take off the lower branches last year to stop them eating it and it looked awful and bare!
Suppose I should be grateful mine have never done the pounce on/tap the baubles off shennanigans but I really do worry about how they could get ill from eating the artificial trees!
Does anywhere sell pet-friendly/safe/non-chewable full Christmas trees?!
