Horror dogs story

I had them for a year.

When they discovered the guest room.

It has huge glass windows looking out.

They could see traffic, cars, people walking dogs.

They took over the room, Ginger and Mari.

I let them, spreading a water proof sleeping bag over the bed.

And seldom checked on them.

Two weeks later, I entered the room.

The bed was shimmering with yellow crystals.

In the light, it was beautiful, almost magical.

What on earth was that, I wondered.

I approached nearer, the sleeping bag was wet.

The two little rascals turned it into pee place.
