Hi Andrew,

It looks like you'll have to declare "_owner" and "owner" before you can reference them in your getter or setter. Otherwise the constructors has no idea what your'e referring to you call them.

If you want to have each pet default to "No Owner" you could define this._owner = "no owner"; in your constructor.

Or you could just use const _owner; but it that'll return 'undefined' if I'm not mistaken, until _owner is assigned a value.

But at the very least, I think you have to declare the variable before it can be used as an idenifier.

I'm not much farther ahead of you, hope I have it right, and explained it well enough!

Hi Andrew!

You are actually missing a closing bracket on your activity getter method, which is causing a syntax error.

If you look at the error message you are receiving you can see at the end where it lists line 19 in the pet.js file. This is a clue that your error is most likely either on that line or right before it.
