Knowing Islay is very jealous, me, being mean, carried Towser on my lap fondling him. Islay got really jealous, and started funny noises and glared at him, talking to Towser to get off in "dog language" which we can't expect Towser the cat to understand! Besides, he's so thick-skinned. So Islay couldn't take it any longer, so again forced him off my lap, and started "mounting" on him, to show who is stronger, and who is above in the hierarchy. BUT again, that is "dog language" which Towser doesn't understand, so Islay, not use trying that on him!
