(eg. description of the frequency and severity of the symptoms

On unspecified date owner applied a partial tube or Advantage II Extra Large Dog to a 10 year old feline. Unspecified date this feline had neruologic signs. Unspecified date owner took to a veterinarian who treated with subcutaneous fluids "to prevent neurologic sxs". The next day the cat was taken to another clinic. Vet bathed cat with Dawn, which seemed to help and put this feline on methocarbamol which made this feline worse. The feline was having difficulty walking while on the methocarbamol. Owner states this feline needed to be flushed internally with intravenous fluids but the vet did not want to overload this feline with fluids as she thought that this feline had a heart murmur and because this feline had fluids the night before. According to second vet, cat was tremoring. Updated information 24.10.2011: This feline was not able to eat while on the methocarbamol. Hematocrit was 20-22 per what the owner remembers. On approximately 10Oct2011 this feline died and was found to be positive for FIV (Feline immunodeficiency virus) and very anemic. No necropsy examination was performed. No more information expected.
