Please, oh pretty pretty please, DO NOT SEND traditional flora to cat owners on these occasions. I went browsing for arrangements this morning, after a friend died yesterday, and everything seems to be either lilies or orchids.
He and his widow are cat people, and these are highly toxic to cats.
When in doubt, Google is your friend, and hopefully the florist is wise to pet safety. One of their humans just lost a loved one, you don’t want to jeopardize the human’s sanity by the felines becoming deadly ill as well. These can be beautiful, but fatal bouquets without immediate and aggressive medical treatment. 
If you receive one, express gratitude, hug them, and do not even leave it in the same room as your cat. I got a lovely bouquet once, didn’t know if it was safe, and I put it outside on the patio. My cats stay indoors.
