How did aunt Clara try to compensate for Lennie's fetish of touching things

Aunt Clara supplied Lennie with mice.

Lennie sat down on the ground and hung his head dejectedly. "I don't know where there is no other mouse. I remember a lady used to give 'em to me- ever' one she got. But that lady ain't here."

George scoffed. "Lady, huh? Don't even remember who that lady was. That was your own Aunt Clara. An' she stopped givin' 'em to ya. You always killed 'em."

Also, at the end of the book, Lennie tells Curleys wife about how his Aunt Clara would give him little strips of velvet to feel.
