Oi Cat!
Book 3 of 8 in Oi Frog and FriendsView the full series
The third core Oi book gives Cat the problem: cats sit on gnats, and Cat is not happy about it. It keeps the rhyme-machine comedy going while adding a clear fairness-and-protest hook.

What’s it about?
The story.
According to Dog, every animal must sit on something that rhymes with its name. Frogs sit on logs, dogs sit on frogs, and now cats are supposed to sit on gnats. Cat is not impressed. As the animals work through more and more ridiculous rhyming combinations, Cat tries to find a way out of a deeply uncomfortable rule. Oi Cat! is another bright, silly, join-in picture book from Kes Gray and Jim Field, full of satisfying sounds, visual jokes and escalating animal absurdity. The formula is familiar by this point, but that is part of the pleasure: children know how the rhyme game works and can anticipate, correct and laugh along. It is particularly good for building confidence with rhyme while still feeling like comedy rather than instruction.

In the classroom
How it works in school.
A riotously funny rhyming series built on rhyme — superb for joining in, predicting rhymes and playing with words.
A book children love that happens to support school — never a stand-in for the texts a class is taught with. Reviewed for the classroom · June 2026.
Why it lands
Why they love it.
Why kids love it
The specific delight is Cat's protest — by book three the children reading know the rule (cats sit on gnats), and Cat refuses to accept it. A small child gets to side with Cat against the system. The first Oi where the joke gets a hint of rebellion.
- Talking to animals
- Breaking the rules safely
- Trickery and cleverness
- Being understood finally
Why parents love it
The Oi where the rule-game gets a fairness twist — Cat objects to her impractical seat, and the rhyme game becomes briefly a negotiation. A useful early read for a child who's starting to notice when things aren't fair. Same airtight rhyme as the rest, with a tiny moral hook.
- Shared humour
- Quick to read
- Bedtime appropriate
- Educational for adult too
