I did ask a while back about platelet counting and they said it was accurate. I believe them because once he got on prednisone after a few days all his petechiae were gone. It just sucks we have yet another month of him on it. The vet I discussed with today said he did see a cat have it and a while on pred to bring levels back up and took the cat off and it never got it again. He said it's up in the air but a great sign pred basically healed him but he's still having immune responses like the swollen liver spleen and lymph nodes .. the nodes arent as big as last time though. He's being more playful at least. And we do a full dose of meds once a day instead of half twice a day. Hes our little Bubble Boy now and can't ever be vaccinated again but I just hope he can recover and his immune system stops being dumbI did a little researching, and only found the obvious...that is is rare in cats, but is also the most common primary hemostatic defect in cats, as well.
I found this article about it that's pretty comprehensive, although apparently written for vets:
Thrombocytopenia in Cats - WSAVA2006 - VIN
It did make me wonder if the platelet counting was automated or not, see this paragraph:
"In cats, decreased platelet counts are a common laboratory finding. However, this is often a so-called pseudothrombocytopenia (incorrect low platelet values) which can occur with automated counting of platelets. It is related to the tendency for feline platelets to aggregate and the size of some of the platelets that in this species can be similar to the size of red blood cells. Therefore, manual counting (e.g., using Thrombo Plus®-tubes, Sarstedt and a Neubauer counting chamber) or slide evaluation must always be done to confirm whether the thrombocytopenia is real or artifactual."
It is heartening that the one patient they saw did fine, though. I'm keeping that candle lit for you both!
