lingering poison pet food symptoms

I have 5 survivors of the poison food debacle.  I lost 5.  Two of them - a male and a female - have weak hind legs.  They are not in pain but I would like to help them if possible.  I was told probably a potassium dip due to the renal problems the poison caused.  No one in my area is familiar with it and I have spent thousands of dollars trying to save the ones I could so I don't want to waste money on a bunch of tests and I do not want them to go thru a bunch of tests.  I have had several wrong diagnoses on a couple of things and I know poison is hard however i had to spend 800.00 when they started throwing up again only to figure out myself the food I was giving them was just too rich for their poor messed up systems.  
When I mention the poison food I am looked at like I'm speaking greek.  I watched a colony of over 50 we had just trapped/neutered/released dwindle down to 3 and, as I said, I lost 5.  I know what I am talking about.
Thank you

I'm really sorry to hear about that.

Are you referring to the Proctor & Gamble (menu foods) food poisoning (melamine in wheat gluten?)


I'm going to start by giving you this link (a number of people on this site have banded together to discuss the outcome to their pets from the poison on this site).

The one thing I know that can help is doing regular intravenous fluids to help flush the kidneys. But I would go to this site, from what I recall, there are folks there who've been suffering through the same experience.

They will need a special diet as well. Melanine poisoning damages the kidneys and puts the cat in danger of renal failure. At this point (assuming it's been a while since the poisoning), I'd concentrate on flushing the kidneys with a few I.V. treatments if it hasn't been done, and then put your cats on a special diet for cats in kidney distress along with following a regular regime of testing to check for kidney function.

Thank you so much for the info.  Yes, I am referring to that tragedy - melamine in wheat gluten.  I now know I saw victims of that beginning in 2006 but in 2007 it became more widespread.  I checked out the site but that tag - survivors of melamine poisoning - appeared to be a blog but I am still looking.  I have a lot of info and would like to talk to others.  I have 5 that I call the outsiders.  They are the first from the colony before I knew it was a colony and they are social with me now.  Not one of them even got sick but there were times when they would not eat the food.  Now I know why.  Two of my rescues would turn up their noses at times but I had older cats who did not even eat wet food at all so I was not concerned.  I would just like to know how those seemed to know.  Hindsight is 20/20 unfortunately
I understand Royal Canin makes a good food for this but they were on the recall list and I am afraid.  I still grieve and worry about the life cut short on the rest.  
You have given me very good info and I feel I can go to a vet with some knowledge.  Thank you very much.
