There was a woman in my mothers group who had this ace little cot enclosure thing lol sounds weird but it was on top of drawers, with wooden frame with netting around it and a shelf thing on top, as they had a cat...She explained to me with a laugh that as they had spent 15 years on IVF to get their bubs and weren't ever to have another they didn't want to take any chances with the cat.
Not sure f you can buy them or hubby built it but it was pretty cool
