Do they take open bags of cat food?

Yes we do take open bags of food. Just seal the top before you donate. These bags of food are given to people who are feeding feral cat colonies that have been spayed and neutered. Thank you for your inquiry. The food can be dropped off at the Fieldhaven Market Place on F Street in Lincoln.

I don't believe so, and I don't believe any shelter does. You can always contact them to confirm
