According to my vet, it's apparently chronic. He said that he has several cats as patients who suffer w/it and he said that it can be particularly nasty. He's loading him w/Prednisolone right now and then he's going to gradually decrease the dosage to see if it comes back. When he examined Coco, he said that he could hear and feel mucous globules in Coco's throat. The first bout that he had caused him to gurgle; this time he just sneezes in rapid fire succession. On Saturday and Sunday he stayed mostly in the basement but after giving him a low dosage of Prednisolone, he began acting like his old self again, getting into everything and being a general pain in the patootie, which is just the way I like it.

Thanx for your input, Katherine, and I'll post if there's any change one way or the other.
