help with raccoon protecting feral cat storage food container

I am a feral cat colony caretaker. Raccoons have been opening a container that has handles and opened another container (I didn't know raccoons have thumbs!) So, I went to Home Depot and bought a plastic tool kit that has two latches and i put a lock on it.

 I went back today and they definitely attempted, you can slightly maybe get a finger but it's difficult.

Does anyone have any ideas of how I can safely store their cat food. I cannot store the cat food inside because the cats are not in my backyard. I have to drive to feed them.

Any ideas would be helpful.

Can you store the container in your car trunk...?

If the car trunk isn't viable, I think they have locking containers at PetSmart.  They are pricey, though.

If you leave food out, the raccoons are relentless.  They will find a way to get to the food.  I would store the food in your care or just bring some with you each trip.  Once the raccoons get into the food, you will also attract other wild life.

Thank you so much for your advice. Just bought a container online from petco

If it works, will yoou share the information about the container?  A lot of people here might be able to use one.  Good luck!

Yes, good idea!
