Cat Figurine with Light and Sound Features
I saw this adorable cat figurine online!!And I was immediately drawn to it. This sparked an idea for me to design my own cat figurine with interactive features such as light and sound. When a button is pressed, the figurine could light up or emit a cat’s meow, adding an extra layer of fun and interaction to the decoration.
Cat Night Light: Touch Sensitive Light
I would like to design a cat-shaped night light with touch-sensitive function. When the user gently touches the cat’s head or back, the light will softly illuminate, providing warm nighttime illumination.
Cat Neon Lights
I would like to design a cat neon light, which is designed with a cute cat silhouette and emits a soft and colourful neon light!
Hi Qianyue, I like your cat brainstorm! Here are some related ideas to help. Please feel free to chat with me on email or slack to discuss further.
for audio playback, I like this board: https://learn.adafruit.com/adafruit-audio-fx-sound-board which can be controlled from your arduino via serial or a digital output.
You already know how to light things up with neopixels, and could put some inside your lamp. you might be interested in “warm white” RGBW pixels to get the color inside your form. https://www.adafruit.com/search?q=warm+white+neopixel
Your form could be 3D printed, how comfortable are you with 3D modeling? There are lots of files available online that you could build upon or modify. For example:

For touch sensitivity, you can use capacitive touch sensing, either with the capacativetouch arduino library (https://docs.arduino.cc/libraries/capacitivesensor/), adafruit freetouch library (https://learn.adafruit.com/capacitive-touch-unicorn-horn), or one of these: https://learn.adafruit.com/adafruit-capacitive-touch-sensor-breakouts
Here are a few guides on working with the neon-like pixel strip to make signs:
