Yes, ulcers in ferrets are very like ulcers in humans. In fact, ferrets have been used in medical research on ulcers. In both cases, ulcers are caused by the helicobacter bacteria (different strains) and the treatment is generally the same as well: acid blockers or reducers (pepcid, tagamet, etc), stomach coaters (carafate, pepto bismol) and antibiotics. My understanding is that amoxy itself may not eliminate the helicobacter bacteria, but should be used in conjuction with flagyl or biaixin for best results. See the ulcer/helicobacter FAQ at Ferret Central for details. <http://www.ferretcentral.org> Good luck with your baby!
