I had it happen to me, I dropped an ASF rat into a tub and as it landed in the tub it immediately jumped like a foot in the air and out of the tub. I swear everything went to slow motion as I tried to catch I mid air and missed. I tried using sticky traps to catch it but would find missing. I was starting to think I was dealing with a super rat until I found it in the tub 3 weeks later. Good thing you found it, only thing worst than a feeder rat running wild is a pregnant feeder rat running wild.
