Cute Pomodoro break timer

When the set time arrives, a cat appears and takes over your screen.
A cute Pomodoro-style desktop break timer.
Because it is a desktop app, Cat Gatekeeper can remind you to take breaks not only while
using a browser or specific social media sites, but also while working in other apps.
----------------------------
Do you get so focused on work that you suddenly realize you have been sitting for hours?
You know you should take a break, but you just keep going.
For someone with too much focus like you,
what you need is a cat that appears right in front of your screen!!
A cute fluffy creature that always interrupts you exactly when you are trying to work.
Cat Gatekeeper Desktop recreates that classic cat-owner experience on your desktop.
Well, if the cat is cute, there is nothing you can do...
After all, humans are merely servants of cats.
We cannot resist their charm.
Supreme beings! Adorable balls of fluff!
Let their cuteness soothe you, and make sure you take a proper break.
