Cocalc/sage coding help!

Here is the code:

Cat=matrix(RR, 2, 27, [[0, 0, 1, 1, 0, 0, 1/8, 1/4, 3/4, 7/8, 1,1, 0, 0, 1, 1, 0, 1/2, 1/2, 5/8, 5/8, 5/8-0.1, 5/8-0.1, 3/8, 3/8, 3/8+0.1, 3/8+0.1], [0, 1, 1, 0, 0, 1, 1.4, 1, 1, 1.4, 1, 3/4, 1/4, 1/2, 1/2, 1/4, 3/4, 1/2, 3/4, 3/4, 3/4-0.1, 3/4-0.1, 3/4, 3/4, 3/4-0.1, 3/4-0.1, 3/4]]) list_plot(mat2points(Cat),plotjoined=True,title='meow!')

Problem 1 A cat is pictured below.
