Care package or hair package?

Mom sent a care package to my Aunt Kelly, who is travelling across the country with a traveling competitive drum and bugle corp -- The Bluecoats -- and before Mom packed everything up, I made sure I got the box good and cat haired-up. Mom thought she cleaned it out, but as Kelly was leaving her message that she got the package, she must have been unloading it because in mid-sentence she said "oh, and you sent me some cat hair!" I just wanted her to know I was thinking of her.
