Always send a response

Lines 3 to 10 in b9f47e9

	function get(request, response) {
	const catId = request.params.catid;
	console.log("catId", catId);
	const cat = model.getCat(catId).then((cat) => {
	response.send(cat.picture);
	}).catch((error) => {
	console.error(error);
	})

Remember your route handlers always need to send a response, especially when errors occur. Here if you don't find a matching cat you just log the error and then stop. This causes the server to eventually time out if the user visits a nonexistent cat page (like /cats/999).
