I don't know how common lungworms are in your area, but Leslie & I rescued a litter of kittens several years ago and if I recall they all had that cough that came & went. A trip to the vets and they were diagnosed with lungworm! It is not common at all in Mass. but it may be what's causing that coughing in Pee Wee. Poor little guy has come a long way since that first day. He's the picture of health in comparison to day #1! Lelsie can probably recall the lungworm incident better than I as I've trapped sooo many I can't recall much lately. Kissies and noserubs to Pee Wee and prayers that all will go well at the white coats. Jan
