I just received an email from Boomer, he seems to be doing well:

Hi Meowmie! This cruise is so great! I have a big room with my own bed that I'm actually allowed to sleep on (don't tell Daddy! he'll get mad that I'm on the bed!) There are lots of purty ladies here that I'm feeling kinda shy. I haven't really left my room 'cept to write you this email to let you know that I'm ok. Maybe someone will stop by sometime? There's lots to do in my room. I can knock stuff into the toilet whenever i want and the maids just pick it up- they don't fuss at me or nothing! there is food everywhere. tuna and salmon an all those other fishies. i did peek into a couple rooms and saw LOTS of purty furr beauties. this is soo great meowmie!
