Logo for CatKindgom eshop

Client is about to open a shop with foods and stuff for cats mainly but it will have foods for dogs and other animals also. So client asked for an intense, distinct and modern font in the colours of the rainbow. Also except the name obviously CatKIngdom the logo must have these words as tagline or something '' And more'' and this Greek words ''Γατίστηκα, λέμε!''. For the last Greek word and its not necessary to add it in the logo if its not fitting well. Also ive attached a logo what client liked as for the symbol of the store (not for the font), it will added as a favicon in the website and in the logo depends on the design.
