Cathy has two cats, Chubby and Grey. Chubby is a fat cat. He likes sitting on the mat. Grey is a tan cat. He likes sitting on the sofa. At noon, while Chubby is sitting on the mat, Grey walks by the mat, his tail held high. Chubby feels uncomfortable. He thinks Grey wants his mat but Grey just passes by. Chubby feels happy and sleeps on the mat. Grey jumps onto the sofa and takes a nap. Both Chubby and Grey are Cathy’s lovely cats.
