Blah, I didn't see the seocnd page, sorry! Anyways, mouse urine has a high ammonia concentration, which is why it stinks so bad, even compared to rat pee. Urine is sterile and does not seem to affect the snake, but it is good to wash off the stink if it doesn't make the snake too nervous after eating... If you can swicth your snake to rats, great, but for now try feeding him three mice instead of two, he may just be a little hungry. From what behavior you are describing, he sounds hungry, that is what my snakes do when they are ready to be fed. Switching from mice to rats can be hard, so try what you can, but some snakes will always prefer mice, the same way some prefer live to PK or FT. again, good luck!
