And that's just what the Fiber Artists of San Antonio have been doing: knitting tightly woven round cozies for baby possums squirrels and birds.
"We either knit them or crochet them but they have to be very tight so that the little possums or birds don't catch their toenails in them," says knitter Vesna Zrinski.
She says they got the idea when a volunteer doing laundry for Wildlife Rescue and Rehabilitation almost washed a baby animal lost in a towel. She says the cozies are washable and resusable and make the babies feel safe.
"I can't tell you how much it tugs at my heart!
When I was first making them ... I was just told that they were nests for baby birds and I have been rescuing baby birds since I was 3 or 4 years old."
Baby orphaned animals of all kinds snuggle up together in the nests by the handful, making it easier for caregivers.
"We make them from special yarn that can be washed and used over and over again."
The group accepts donations of washable durable acrylic yarn that is also of course, soft.
