I am seeking the title and author of a children's picture book I read
in the time frame of 1964 - 1972.  A child (a boy, I think) built a
little house for his pet turtle.  As he acquired more and larger pets,
he added on to the house, stacking the smaller pet houses atop the
larger ones until finally, he had a horse's stable on the bottom, and
at the very top of the stack of "houses" was the original turtle
house.  This may have been part of the "I Can Read It All By Myself"
series, but I don't think it was written by Dr. Seuss.  Thank you.

Hello.

Your book is "Why I Built the Boogle House" (1964) by Helen Palmer.

See this description from a dealer listed on Abebooks.com:
" A boy builds a house for his turtle. Other animals come to live when
the turtle moves out. The house gets progressively bigger! "
