Haven’t read all the comments yet but thought I’d pitch in with a breeders point of view :) There are some really legitimate concerns about home visits that myself and some of my breeder friends have
I’m a TICA registered cat breeder (obviously not the same thing but reasons are similar) and honestly I really don’t like people coming to visit my home, and absolutely not before a deposit.
This is not because I have anything to hide, (if someone was really concerned I’d be happy to do a FaceTime walking tour of my entire house and garden if it put someone’s mind at ease) but more for my safety as giving out my address to anyone and everyone who says they’re interested in a kitten is a huge security risk, especially when theft of cats is at an all time high in the UK.
I am happy to have visitors when my kittens are A. Old enough that they’ve had their first set of vaccines (I keep kittens until about 14 weeks old when they’ve had both vaccines, I don’t allow visitors before they’ve had any vaccines as at this age they are very vulnerable to infection and increased visitors could be a risk, for the same reason I don’t even let friends and family meet them without a lot of sanitisation) B. have had a deposit put down on them, I’m disabled and allowing strangers into my home and giving random people on the internet who know I have multiple high value kittens my address is incredibly dangerous for the safety of me and my kittens, if someone it interested enough to do multiple video calls, sign my kitten contract and put down a deposit it helps weed out potential security threats and at that stage I offer a visit whilst they wait for the kitten to be old enough to bring home. I’m still TTC but once we have a baby this would be an additional reason to be uncomfortable with large volumes of visitors. There’s even cases of people being MURDERED by someone who has come to their house to see a puppy, the risk might seem minimal but there is definitely a risk.
However, I ALWAYS offer a video chat (sometimes multiple) with people who are interested so I can show them my kittens, my home, and where the kittens are raised and answer any and all questions, which helps to make buyers more confident (and shows that I’m a real person and the kitten is real and with me and I’m not a scammer who has stolen photos or made them with ai) before accepting any deposit. I also have a comprehensive kitten contract which legally protects both myself and the buyer that I ask to be signed before taking any deposit.
Many of my breeder friends also don’t accept visitors for similar reasons (disease risk, and for their own protection).
So to summarise (so you can see it from a breeders point of view), if a breeder doesn’t accept visitors this isn’t necessarily a red flag on its own, but the context is important. If they don’t accept visitors AND refuse to do video calls to show you their home, puppies/kittens, where they’re raised, etc ahead of you putting down a deposit, that’s when you should run :)
Puppies available in autumn also is not a red flag UNLESS they’re asking you for money right now, they shouldn’t ask for a deposit or anything financially until there is a puppy born and they’ve gone through the first few weeks (for kittens, they can pass from fading kitten syndrome unexpectedly in the first few weeks, so really should never be promising them to someone until they’re a few weeks old and past the more vulnerable stage to avoid heartache) but ready in autumn means they’ll be old enough to take home in autumn (I have a cat who is pregnant at the moment and based on pregnancy length and how long they stay with me, they will be ready to go home in autumn, however I would never ask for a deposit until the kittens are a few weeks old.
There are breeders out there who seem great but ask for a deposit to be added to their waiting list (rather than a deposit on a specific puppy/kitten). Avoid this at all costs. There was a notorious breeder in the UK who was exposed for horrible breeding conditions and she shut down because of it, but kept the TWO YEARS worth of advance ‘waiting list deposits’ she had and vanished without a trace, even moving house, lots of people never got their money back (she was also charging over 100 to be added to this list so not a small fee).
However in this case, I have to say that them offering to bring the puppies to you for a visit seems weird to me.
