Cats will play with anything and probably everything. You don’t need to spend a fortune to keep your kitty entertained and if you want to keep your fingers and toes intact than let me offer some suggestions.
I found a lot of my cat toys at the Dollar store and thrift shop.
I must admit I am quite tempted at buying that toy they keep showing on toy. The one with a cloth circle and a mouse goes around in a circle, but being frugal I can’t justify the cost so I won’t buy it.
