Positives about p@h, - rabbits and guineas separate, all animals appear clean, in my store I have only ever seen one sick animal; which they did take out the back, they have leaflets in store for advice, they honestly say when a hutch is not big enough for a rabbit, some members of staff attempt to gain knowledge, at least they offer compensation/pay the cost of vet fees for sick animals.
While I agree that people who can sex animals should check the gender themselves before buying, the fact is that lots of people just walk in, wanting a pet for their kids or themselves, they don't know any better with regards to getting an animal from a rescue or somewhere where it's guaranteed health
In reality a lot of people don't think through having pets, what they need, why different animals need different things, and the responsibility they're taking on. Which of course is why so many end up in rescues.
So the fault is with the buyer, for not researching properly, but it's also the fault of not just p@h but other pet shops for allowing the accessibility of these animals - I bought 4 guineas from p@h in 2003/4, just because I wanted guineas and remembered them from my young years. They looked healthy in the shop, were healthy and 3 out of 4 of these are still with us! But what gets me is the ease of sale - I was simply asked if I'd had guineas before, were they going to live alone, did I already have a hutch and food, ok, that'll be however much please. It does depend on the member of staff though, my 1st & 2nd guinea were sold to me in that manner, but the 3&4th the member of staff was much more helpful, took me round the store to find things I needed, suggested things to me & was generally making a sale, but a responsible sale
