(AP) — The Nebraska Humane Society is offering free cat adoptions to open up space.

The group says it’s offering the free adoptions between Wednesday and Friday. The eligible cats are six months and older.

The Humane Society says the measure is aimed at making sure the group doesn’t run out of space. It says it summer cat population has surpassed its adoption rate.

All the cats are spayed and neutered, as well as vaccinated.
