325N: Children’s book of holiday stories from 60’s/70’s?

I was born in the late 70’s and my mom would read to me a used children’s book of holiday stories with anthropomorphic characters. I remember an owl (or maybe a family of owls); a mouse that ate paste in the Valentine’s story; a Halloween story and a Christmas story. I seem to remember the cover was orange and the illustrations were in black & white with a dash of orange. The illustrations were definitely done in the unique style of the late ’60s/early ’70s. Any ideas?¬†Thanks!
