I did not take away the suet which the birds liked so well. I got some tin sheeting and tacked it around the tree. The cat could not climb over the smooth sheeting.

Imagine my surprise when I saw her up there at the suet again! “How did she get there?” I wondered to myself. Day after day I watched Kitty before I found her out.

One morning, who should go climbing up that tree but a red squirrel? When he reached the tin, he looked around and made a loud chatter. Seeing no one, he took one big jump over the sheeting and went to the suet. After tasting it, he wiped his mouth on the bark as if he did not like it. Then he went over to the bluebird house. The entrance to this little house had been nicked by somebody with sharp little teeth. Now I found out who that somebody was. This squirrel was even now nibbling at the entrance, trying to make it still bigger. At the wren house somebody had broken off the little porch, which was probably the squirrel’s doing also.

I wondered what I should do to keep this squirrel from spoiling my bird houses. Some more tin sheeting, I thought, would fix it so he could not jump over. I put another sheet just above the first one. That made the tin protection thirty-six inches deep. When the squirrel came the next time, he climbed as far as he could, then looked up at the tin. That was too high a jump. He turned, jumped to the ground, and scampered away.

The pilfering red squirrel is not to be confounded with the genial gray squirrel of our parks, who loves to take peanuts out of our hands.

I still wondered how Kitty had made her way to the suet, with the tin around that tree. Surely she could not jump over the tin! As a jumper the squirrel can beat Kitty any time. One day I heard a scratching noise. Kitty was sharpening her claws on the bark of the next tree. Every little while she climbed a few steps up that tree; then sharpened her claws again. There was nothing in that tree that she could harm, so I let her go on. She walked along on one of the branches, and jumped across to a branch on the other tree, the one that held the bluebird house, and smelled around there. It was early spring. There were no young birds in the house yet; so I let her go on, just to see what she would do. Some English sparrows had started to nest in the little house. Kitty pulled out grasses and feathers, and spoiled the nest.

Now just think how wise she was to plan that all out so nicely! And all she gets for it is scolding! Why should we blame Kitty for liking birds? We like our chicken dinners. We praise Kitty when she catches a mouse or a rat. Some people even entice her to catch English sparrows. How can she know it is good to clean out a mouse nest and naughty to clean out a bird nest?

Two things can be done to lessen the loss of birds by cats. First, to safeguard in every possible way every bird house, feeding place, and bath. Second, to compel the owners of cats to keep them on their own premises, and to lock them up nights. It is at night, when there is no one to interfere, that cats do the most damage to birds.

I knew that if Kitty could jump from that tree to the next one, the squirrel could do it, too; so I put double tin sheeting on that tree also.

But such a clever cat and such a nimble squirrel would also know how to climb the grape arbor, I thought; so I took the wren house off the arbor. This house also had been nibbled and the entrance made much larger. I concluded that the worst of all places for a bird house is a grape arbor, a pergola, or a garden arch.
