My four 12 months old cat randomly started having seizures about 1.5 years ago. At 1 stage they were so undesirable she was receiving them 3x per week. For the very first year we changed her to some grain free meals, and that stopped the seizures, but only quickly. http://garrettefjjm.tinyblogging.com/The-best-Side-of-What-are-the-terpenes-you-should-look-for-on-a-Certificate-of-Analysis--37777033
