Question for Dr. Susan - tongue ulcers

[Wheezercat42]

Hi Dr. Susan,   I have an FeLV+ cat named Legolas who has been fighting ulcers on his tongue since January '03.  He has enlarged kidneys, typically has a PCV of 13-27%, is still active even when his PCV is 13%, and is getting 300cc's of ringer's lactate a day.  We've been gtiving him Depo shots - often once a week, which helps some, but hasn't allwed his ulcers to heal completely.  When he's due for another shot, he drools profusely, after his shot, the drooling stops.    We've tried amoxy, baytril, & clavamox - all of which had little effect.  He's had periodic doses of epogen for his anemia (which boosts him from 13 to mid/upper 20%s.  He's been holdinng his own with his weight at just under 8 pounds - last December, he was up to 12 pounds - before the ulcers.  I've been giving him canned food every day in addition to the dry food the others have to eat (I have 6 positives living seperate from the cats in the rest of the house).   I've had slippery elm bark recommended for him, but I haven't been able to try it yet (haven't gotten any yet).  Is there anything else that might help him and will the slippery elm bark cause any problems with his kidneys?  He urinates a lot (that's what tipped me off to get some bloodwork done on him in Aug. '03 in the first place).  What would be a safe dose for him?  Thanks for your time,      Determine that the thing can and shall be done, and then...find the way ~ Abraham Lincoln Kathy
