Also you should give your cat a wormer every month there are over the counter wormers you can get at wallmart and pet stores that only cost about $6 to $12 dollars that you give to your cat with instructions on the box just make sure they are the wormers that cover all worms instead of just one kind of worm.
Carry-On Size Limits. All passengers on American Airlines flights, regardless of class, are allowed one carry-on bag, which can weigh up to 40 pounds. Carry-ons must also not exceed 45 linear inches; this is the sum of the bag's height, length and width. Alternately, you may bring a hanging garment bag in the place of a standard carry-on.
This applies whether the flight is domestic within the US or international. Most flights that originate from outside the US have a weight limit for total checked baggage-a miserly 20kg/44lbs if you're traveling in coach class, 30kg/66lbs for business class and 40kg/88lbs for first class.
