Cat is owned by a brother and sister. They constantly dress him up like baby, even putting him in a stroller. He decides that he’s had enough and he runs away. He goes somewhere cold (maybe Alaska, or somewhere similar). He then goes ice fishing and catches a fish. He has no one to be with. He realizes he misses the kids and goes home to them. At the end up the book he is all dressed up and says something about this not being so bad. It was made around the 90’s. The cat was either a tabby or grey.
This sounds like ‘Polly’s Pet’ – a Little Golden Book by Lucille Hammond.
“Tired of being poked at and fussed with, Polly’s cat runs away from home and experiences absolute freedom, only to decide home with all its faults is the best place to be.”
And from an online review: “The little cat is tormented by his loving but rowdy owner children. He gets dressed up in baby clothes (just like I used to dress my cat up) and pushed around in a baby carriage. He never gets peace for a nap, etc. He finally decides to run away. For the first few days, he does everything he never has a chance to do at home (I’ve been there, done that!), but after the first few days, the excitement wears off. He begins to see that there is no one to see his snowman and be proud of it. No one to ice skate with, etc. He see the other pet owners with their pets and he misses the children who own him. He goes back home, and while things are no different, he doesn’t mind so much because he loves them and he wants to be home.”
