Your favourite jumper. Preferably in the exact opposite colour to his fur, but some thoughtful cats will carefully cultivate an undercoat of white/grey/palest beige to ensure that any owners thinking 'Ha! I wear black/dark colours, so a black/brown tabby cat's fur won't show' soon find out that the fur's visible on all clothing.
A second and third selection of bowls, some angled/raised, some flat and wide in case the whiskers or chin are offended at some point.
Flea comb.
Deshedding brush.
Gentle hairbrush.
Bristle brush and toothbrush for cheeks and under chin/something to murder whilst flea combing is going ahead.
Claw clippers if an indoor cat. Doesn't harm them to nip the very sharpest needletips off, saves some of your legs/tights/wooden furniture/new carpet for a couple of days.
Have you got another expensive and favourite top or two?
Insurance or a healthy bank balance. Or both.
Washable sofa cover. Don't ask me why.
Waterproof mattress protector. Believe me, you don't want to know.
Gluten/grain free cat food from the outset. Finding out why is traumatic.
Pet safe floor cleaner. Just because - no point getting an animal and then poisoning them because you didn't realise Zoflora's deadly.
Fake fur throws for bed, sofa, armchair, your legs.
Spider plants. Makes up for the lilies, arums and other plants you can't have anymore. And small bonus for the cat, they're mildly hallucinogenic, so you have enrichment in getting to the spiders - and drugs.
For toys, other than hands, feet, dressing gown belts, laces when you're in a hurry, hairbands around your wrist (PING! Wake Up!), a strong thing on a rod and a kickaroo have been the most popular.
