Insulated shipping boxes (Lakewood, Kipling & Jewell)

I have these great small insulated boxes I get from Chewy with my cat's meds that I would love to be reused. 10x8x12. I have one that isxa little larger.. They include the freezer thingie that keeps everything cold. I am at the point that I will have to break down & recycle the parts that are recyclable. I hate to do that. I'd be happy if someone could give me ideas of what to do with them if nobody wants them. Thanks! Porch pickup.
