Looking for a small lid for small cat tins.

Pet food stores should have them. They may even be free with purchase. I know I have 1 or 2 in my cupboard from the few times I needed to feed my dogs canned food in the past, and I certainly never bought them.

I have a couple different ones that I just picked up at the grocery store. They fit on both large and small cans - have a separate edge for smaller cans. I also have one that I got from the vet's office when I got smaller cans of prescription food there. Good luck!

I haven't bought any plastic lids for a while, but typically the plastic lids sold at the pet stores (and probably even in the grocery store) have a ring in them meant to fit the smaller cans as well. It may not look like it, but pick one up and try it on a smaller can at the store. It should fit. If they don't, there is a brand that comes with a black plastic lid that you can use on other cans. They aren't super tight and are probably only good for a day, otherwise I have used saran wrap and a rubber band. Good luck P.S. there might be some inexpensive small containers that are meant for people food that you could use for cat food

You mean the size for 3oz cans? The ones for 5oz cans are pretty readily available but I have never seen a plastic lid for the 3oz ones. You could transfer it to a small tupperware.

we just put the can in a deli container, you know the kind they put potato salad in, if we don't have a lid.

works out just fine

I just use a round Rubbermaid container.
