This is my periodic WARNING ABOUT FLOWER ARRANGEMENTS AND CATS. LILIES of ANY kind are poisonous and will kill your cat.
With the holidays arriving and people giving and receiving arrangements, I want to take the time to caution people about the small lilies florists often put into arrangements that many might not know are deadly to our cat.
The pretty tiny accent flowers are what you’re looking for. They come in many colours and are often used around the larger ones to fill in spaces.
Edit: and yes, I included the “alstroemeria” because my vet said those can be very toxic and deadly in some cases with older cats, compromised immunity, or kittens. So, better safe than sorry. YES, they are listed as “non-toxic” but they do cause severe complications and can impact a cat immensely.
The alstroemeria is distracting to people who need to point out a lot of places say they’re non-toxic, causing only mild stomach upset and the runs… which in a cat with UTI or an older cat with kidney issues…is not something they can possibly survive. Bee stings are non-toxic unless of course, you react badly to bee stings.
So lilies… not good. No bueno. Keep your kittehs safe 
Keep the arrangement for sure but remove the flowers and dispose of them before your often curious cat nibbles on it. Anything on that flower… anything… is poisonous. Even if your cat is old and hasn’t shown an interest in anything but a can opener in years… it’s not worth the risk.
And oftentimes, you won’t even KNOW they’ve nibbled on that flower.
“Members of the Lilium and Hermerocallis genera are toxic to cats. This includes: Easter lilies, day lilies, Tiger lilies, and Stargazer lilies. … All parts of the lily – including the stem, leaves, petals, stamens and pollen – are poisonous to cats.”
Thank you! I didn’t realize they were a problem for cats.
