@AnnaNanna not all cat matters are straight forward

Outdoor cats will come back inside to use the cat litter: would you not rather use your own toilet than a public loo?
You need a cat litter even for an outdoor cat if you are not planning to ban him form your bed overnight ... it would be cruel

Friends and enemies will have access through the cat flap. Mice are easy to sneak in while you are not looking

A cat flap can also cause stress for the cat: could you relax knowing your door was wide open to all in the street?
Flea treatment needs applying every 4 weeks: the cheapy supermarket one will not so for an outdoor cat, buy online, budget about £ 15.00 for a box of 3 treatments. You might get scratched

Yearly booster vaccination for an outdoor cat are more expensive, about £ 40.00 for mine last year.
My BigCat came to stay out of the blue, had him "done" at the vets, developed a personality disorder that resulted in self-harming (ripping his fur out) cost me a fortune in meds, has been sick on my new duvet, shoots only on
my strawberry beds, eats like a tiger, paws me at 5am 'cause he's wanting out and bullied away the other cat of the house.
The joys
