Persians are just the best!
I had two long haired identical sisters from a rescue. I was a complete Persian novice, but they've been really easy. I wouldn't have another make of cat!
Affectionate, docile, cushions that breathe. Not very bright though. Mine go into an enclosed garden, but aren't overly bothered by it. And don't miss it if they don't go out for a while
Grooming wise, mine have been fairly easy. I brush them both every few days with a tangle teaser and she gets a good doing over with a metal comb every couple of weeks. I take her to a professional groomer every 3-4 months as required. Mine had very easy coats. Some are more difficult.
My pair hate having their eyes cleaned and Tbh tend to clean them themselves. Wiping is a no. But I can pick off the dried on gunk with a fingernail.
Persians are prone to health issues though. So good insurance is a must. We've run up £16k bills. And Maia died from inherited heart disease. Which Magic also has, but not as severe. Magic has a very tiny nose so sounds very bunged up and does struggle. Bothered me more than her though.
I now have an exotic called Cheddar. (See multiple posts!) she's noisy, very gentle, super affectionate and utterly bonkers!
Go for it OP, you won't regret it!
