For a happy story...
Our old kitty, Mojo, was the world's ugliest cat. Scruffy, ratty even with good food and being inside, mud colored. Very stand offish, didn't like to be around people. In June 18 years ago, he was inside with us to heal up from a nasty fighting abscess, then we were going to let him back outside.
DS was in his crib, 5 weeks old. Mojo always just sat in the room with DS, not in his crib, but just in the room. I was tired and laying down while DS napped. Mojo came TEARING out of the room screaming bloody murder, leapt up on my chest SCREAMING at me, ran back to DS while screaming, full fluffed up and was just making a horrid sound. I got up and ran to DS, thinking Mojo had done something. DS had stopped breathing. Once I picked him up, he woke up and started breathing again. Well, I'm a paniced 21 y/o new Mom, took DS to ER. He had early stages of RSV.
Mojo never did go back outside. He was buried out by the rose bush 4 years ago. Still miss his ugly mug.
