Simple doubt: can I keep one v-pet alive?

Hello, reddit strangers. I've been thinking of getting a v-pet of the pendulum color collection.

However, I'm a teacher and work with kids ranging from 6 to 11 years. Because of this, I'm not able to take care of the v-pet during class, so my options would involve sneaking out, which could end bad for me, or muting and hope for the best?

I learned about the muting function, but not if there is a way for working adults to manage precious little digimons. So, I'm questioning this as it's not a buy I can afford I can't enjoy at all. Huge taxes and all.

Is there a way or should I rethink it?
