Hi! Trying to find a book I read in my childhood. It was a children's book with 2 cats as the main characters. I believe they were friends who went exploring and found a robins nest. I think (if I remember correctly) the conflict in the book was one wanted to keep it their secret, but the other cat told others. I know one cat in the illustrations has white fur, and I think the other was a calico. I read this in the mid-late 90s, but it may have been a hand me down from my older sister who would have gotten it in the mid 80s. Any ideas are appreciated. Thank you!!
