So let me take you through this photo. Theo is an Abyssinian cat and Loki is a Bengal cat - they're both a year and a quarter old. For their safety they don't have free access to outside - I put walking jackets on them and take Loki on a retractable leash and Theo, who tends to stay within sight, is off leash. My other half will sometimes walk Loki while I entertain Theo with a wand toy. On this occasion I attached a small leafy twig from a bush to the string on the wand and Theo went mad chasing it in the garden. When he caught it he then dragged it back into the hall and when Loki came near to investigate what on earth Theo was doing Theo growled at him to warn him not to steal the twig off him.
tldr; Theo's a few sandwiches short of a picnic
