I've never had any problems with anything, but toxoplasmosis can be caused by raw meat. It is easily killed by being frozen for a couple of days in a household freezer, most meats in the store have already been frozen so it's not usually a concern, it's more of a concern in wild caught meat. did you freeze your meat before feeding it? It can be very harmful but usually the most severe cases occur in cats who are already ill, are immuno-compromised or are over vaccinated. I have also heard kibble fed animals getting toxoplasmosis, probably from some other source.
I really hope your kitty gets better no matter what illness he has. I would not stop raw feeding but I would be diligent about freezing because it does indeed kill the toxo.
