Our pets can't tell us they're too hot.

The coolabah is the tree every Australian knows from a song. It grows where the country runs hottest, along dry creek beds, and its wide canopy throws the shade every animal heads for when the heat sets in.

At our place in Brisbane, summer looks the same every year. By 2 pm Red, our kelpie, is flat on the bathroom tiles. Mango, our ginger cat, has given up on his water bowl and is waiting at the kitchen tap for someone to turn it on.

They can't tell us they're too hot. They just go looking for somewhere cooler, and for water that moves. So that's what we set out to give them: a cool place to lie down, and fresh, moving water wherever they spend the day.

We'd like Coolabah to keep feeling small, however big it grows. One-time prices with no subscription, a 90-day guarantee, and a real person on the other end of every email. Often, that's me.

Thanks for trusting us with your best mate.
