Happy Pets INSTA-GROW formula for Puppies and Kittens

Happy Pets has added a new feature for those of us who want to speed up our pets' growth -- players can now buy a new insta-grow formula that will turn puppies and kittens into full-grown animals in a matter of seconds. Of course, skipping to kitty or puppy adulthood will not be without hardship -- insta-grow formula will cost you 20 Facebook Credits, roughly the equivalent of $2.

We've documented the insta-grow process in our step-by-step guide below:

First, click on the puppy or kitten you want to insta-grow. After they have been selected, click the "insta-grow!" button in the pop-up menu.
