How do you catch a Abra?

I used the type of ball that catches pokemons easily in the beginning of fight cant remember name though.

You can catch them on the route where you catch the Kadabra...

Since it teleports away right after you attack it, just throw an ultra pokeball at it and you've caught it. Or at the GoldenRod City games place (where you play games to earn coins to unlock...

go to the bushes and walk around until u find one or go to the mountains

Abra can be found on Route 24 in the grass when you find one it will always automatically use Teleport so you must use a Pokeball immediately if you want to capture it which makes it very difficult...
