I'm looking for a book I had as a child in the 1970s, though the book may be from the 1960s. It was a small paperback with a light blue cover. It was about a cat, I think named Henry, and his mother. The drawings were very simple pen & ink drawings. There may have been a little blue in the drawings too, but mostly I think they were back and white and were simple. The cat was always getting in trouble, and had to be sent to his room. His mom was cooking in the kitchen. They both walked upright - and the mom wore an apron. I think it may have been a series and there were other stories about him.
Try this: Take a Nap, Harry, by Mary Chalmers
Yes!! That’s exactly it! Harry not Henry! Thank you so much!!
You’re welcome.
That’s the one I was thinking of! Not sure if it’s what OP is looking or not!
I know those books; they were favorites of mine. I can’t remember the titles or the author, but I will search for them too. I thought one of them was “Go to Bed, Henry” but googling brings up nothing.
Take a Nap Harry by Mary Chalmers. From the comment section above, I didn’t figure it out on my own! but thought you’d like to know too.
