Cant I request a dog to be put on hold for a couple of hours until I can get there from work?

Meet and greet then adopt but meet and greet is mandatory

You have a dog and want adopt a cat is meet and greet necessary

Meet and greet first

Yes. But you would have to have done a meet and greet first

Call and ask.

I'm sorry, that's a question for SPCA staff. Good luck.
