Cats will only visit your yard if you put out food (regardless of what kind of food you put out). But you also need toys to let them play. They left fish when they leave your backyard. Yummy!
Save the fish in order to buy more expensive food and toys!
Sometimes, fish are accompanied by a memento. But mementos need time as there is a certain number of visits for a cat to leave a memento. Each cat has its own memento so you will never know what or when they will leave. It's a surprise!
Expensive toys will garner you rare cats. Yes, RARE cats!! Better save up and use those fish for rare cats.
