Lily Pollen?

Hello! I have a 3 month old long haired boy that I brought home about two weeks ago. My roommate went out of the country and left a bouquet of flowers her bf got her. There were a few different flowers, but there was a lily or two, and a couple of roses I think.

I threw away the bouquet and water, vacuumed the area, sticky-taped the carpet, sprayed with enzyme cleaner, and wiped my kitten down with hypoallergenic wipes, but I’m still a little worried I missed some pollen or that some got in the air? Is there anything else I should do or am I being overly anxious?
