Identify (and delete) all .gif files with more than 1 frame in all subdirectories

Question

I having the following linux command to identify all .gif files and list its frames in the active directory:

identify -format '%n %i\n' -- *.gif

Now I want to modify and expand the command to fullfil the following:

1. indentify just the .gif files with MORE than 1 frame

2. look also in all subdirectories (right now the command is just looking at the active directory)

3. a command to: a) list the identified files b) delete the identified files (more important)
