Females are given skirts and pants. You can choose to wear either, but you will always get one pair of pants and three skirt. So, lots of laundry if you do a lot of flights! Perhaps it is possible to buy an extra pair at own cost, but I do not think you can- it is usually for replacement only.
Pants are RECOMMENDED for Saudi flights (RUH,JED, MED, *especially* during Ramadan) but this is not enforced.... yet...
I heard a rumour that the tattoo rules still applys for females because pants MAY be phased out one day. Do not know if this is true or not, but I would follow the guide for now.
Pets- you may be able to take your cat (even if it against the rules) but will you be able to bring it BACK again? In Australia or UK, quite difficult I heard. you need lots of papers and can be very expensive. Better to get someone you know to loo kafter him/her. And perhaps give a home to a cat here in a shelter if you must have one. Pleanty of them around
