my mom heard tigger meowing in a neighbor's backyard. she rushed over to the next street, knocked on the neighbor's door and told her our cat was back there. our neighbor wasn't aware of it and was happy to let my mom back there.
funny thing seeing my mom carry tigger through the front door, seeing how she says he annoys her a lot (all the meowing and need to be petted). but i think she was as happy to see him as i was.
from the looks of tigger, it appears he just wandered off. he might have gotten scared or curious during his travels, which would account for the amount of time he was gone. of course my mom still thinks he was cat-napped by some kids.
