Hahahaha^^^^ oh i love that story about the cat, can't tell you how many I have about my burmese who seems go missing every time we move. One night he actually got out when it was raining once and the next door neighbours had dug up all the sewerage pipes in their yard, i was looking for hours, and then he comes running up to the porch covered head to tail in mud. And he looked at me like im home now mum dinner time!
OP don't feel bad
its part of the hole process! All the stress and fussing over your new baby will go away eventually! I know I fussed over my dog for aaaaages when she first came home. It's a funny story you can all remember later on.
