Donohue, 17, averaged just under 19 disposals a game in his 16 appearances with the Falcons this season, playing in several positions around the midfield.
Geelong national recruiting manager Stephen Wells said the Cats had kept a close eye on Donohue's progress over the past 12 months.
"Adam spent a little bit of time doing testing with our VFL squad and he's got a lot of improvement left in him," Wells said of Donohue.
"The boy's got some fantastic kicking skills and we feel that if he got into our program, we think that he can develop well with us as a forward-flanker or midfield player."
"It will be interesting to see if any bidding does occur. If it does, then we'll reassess our position."
