OMG!!!!! I just noticed this thread, and after reading that, it makes me wonder if what made me originally join the TCS website may have been due to Bio-Spot. Last summer, I originally posted here regarding Samson. He had started sleeping in the litterbox, I thought he was just upset that my Mother--in-Law had outstayed her welcome as far as Samson was concerned. Now, that I see this post, I remember that I had used Bio-Spot on Samson, since all 3 of my cats had quite the nasty flea problem last year, even though all 3 cats are indoor-only. I now wonder if Bio-Spot may have been what made Samson ill. When I had taken him to the vet to find out the cause, I didn't think to say about using Bio-Spot, other than to mention that I had treated all 3 with it to get rid of the fleas. The vet didn't mention anything about the fact that the Bio-Spot could have been the cause for Samson's behavior change....he just agreed with me that Samson was upset about the change in the household. And, at the time, I felt the vet was right...within a month or so after my MIL had finally left....Samson was totally back to normal...well, behavior-wise. He finally within the last month grew his hair back fully....his tail was very thin in fur, and he had a bald patch on his back. I don't totally want to blame my vet for not saying anything regarding the use of Bio-Spot...especially since only Samson was sick...so even I didn't think his issues could have been related to using Bio-Spot. Neither Emmy or Ranger acted "off" after their getting treated with it.
Now, I realize (hopefully) that the form of Bio-Spot I used last year is the original product....but I can say for sure I WILL NEVER use that product again!! Although, I am happy to say, this year was flea-free.....I dread to think what would have happened if we had had the flea problem again, since I wouldn't have known to stay away from Bio-Spot, and it probably would have been me posting of this tragedy happening to one of my cats...or even more.
I am so sorry Sunnicat for the hell you have been through....but I am so grateful that you shared your story and information that you gained through this horrible tragedy. Although it doesn't ease your pain, please take some comfort in the knowledge that through you, Sunni will not have died in vain.
