Unless you have an older house or your cats are very smart they will be under the bed or furniture. Welders gloves are ideal but they are going to want to stay when you grab them. That means you have 2-3 seconds between the time you grab them, rip them from whatever they are holding on to and throw them in the cage.
Always grab the back of the neck and just pull. I know that if your wife is reading this she may freak out but unless you are just pulling on the tail or hind feet it is kind of hard to hurt them compared to what they will go through if they stay.
Having dealt with my cats and feral ones over the years yours will be a piece of cake.Of course smart cats do not go under the furniture or bed. They learn to open cabinets and stuff all over the house and hide there.

Collar with a bell if they are indoor.
