Sounds like you had a great day GF! Very multicultural!! I guess if you have just had the shortest day of the year, we must have had (or are about to have) the longest day of the year!
Put in some cat grass so that they will be attracted to that instead of your herbs. They're probably just after something for their digestion if the cats are solely indoors. Other than to have a sniff, mine ignore the herbs and go to their cat thyme plants, normal grass or anything that is more interesting than a static herb!! LOL
Too many restaurants, not enough time...
