In Deathly Hallows, Scrimgeour tells Harry, Ron, and Hermione the following regarding the Golden Snitch:
‘Correct,’ said Scrimgeour. ‘A Snitch is not touched by bare skin before it is released, not even by the maker, who wears gloves. It carries an enchantment by which it can identify the first human to lay hands upon it, in case of a disputed capture.’

I re-read Quidditch Through the Ages and parts of Deathly Hallows and Philosopher's Stone and couldn't find an answer to this question. Anyone who's played a sport before will know that an integral part of learning the game is, obviously, handling the necessary equipment for a given position, i.e. a Seeker might need to practice catching hundreds of Snitches in many, many practices to really get a feel for the position and the game.
Are there practice Snitches of some sort for Seekers to use? Are there any canon references of what equipment Seekers use to practice? For example, in Philosopher's Stone, Harry is picked for the Gryffindor Quidditch team when McGonagall sees him catch Neville's Remembrall -- I can't recall offhand any other scenes like that one, where a Seeker is catching an object other than a Snitch, but perhaps I'm overlooking something?
So, how can a Seeker practice if the Snitch can't be touched prior to a Quidditch match?
I'm aware of the scene in Order of the Phoenix, in the chapter Snape's Worst Memory, where James Potter is showing off for either Lily or a group of girls by playing with a Snitch and repeatedly letting it go and then quickly grabbing it up before it can get away. I don't think this is a particularly good example to use to answer my question because James was actually a Chaser (Yes, I know he's named as Gryffindor's Seeker for the year 1969 in the Philosopher's Stone film, but canon/J.K. Rowling both have him assigned as a Chaser.). I don't recall if it's explained where he got that Snitch from.
ETA: I'm looking for an answer based in book canon: The seven novels, Quidditch Through the Ages, J.K. Rowling interviews, or information from Pottermore, for example. I would want to know where in canon it says a Snitch can be used more than once in game play (which would include practices or scrimmages).
