I have a very tiny kitchen and a very annoying cat who always gets into the trash! She rips the bag right out of the bin and I wake up to find shredded bags all over the kitchen and on occasion she gets food out of the trash. After trying everything I thought about under the sink. She never gets in there and I'll have more space in my kitchen.
I found this cheap little trash bin at Conway for $2.50
I screwed the bin onto the cabinet.
Close the door and you are finished! Quick 5 minute project.
