Ashy is stunning! I'm so glad she likes the toys you bought her. Along with toys, many people have found out that their cats have more energy after removing dry food from their diet. Cats are meant to eat meats, but dry food is mostly grains and cats just don't derive much nutrition from it. There's a great forum on feline nutrition here on TCS; I recommend you explore it if you're interested in learning more.
Personally, I've learned a great deal there and it's been a lot of help now that I'm trying to provide a species-appropriate diet to my two kittens. They are about 9 weeks old; we haven't had them even a week and their energy is now through the roof. When we first brought them home on Monday (and even before then, when we'd go visit them) they were docile and even a tad lethargic. Since Monday they've only eaten things like chicken, beef, eggs, organs and some canned food. No longer are they lazy, slow kittens! Now they spend their playtime chasing each other all over and giving heck to their toys!
Edited because a kitten just ran across the keyboard and posted this before I was ready!
One toy that mine like is made with a toilet paper tube.
