Judy that PetSolution RX really works great doesn't it...i kinda 4got bout it cuz i have it 4 King...i use it anytime he feels a lil itchy or scratches sometimes....This woman ur talking bout kinda sounds like my boss....cuz she says she uses the PetSolution RX on herself too...i would not try it myself...but thats just me....if they r ant or someother insect bites, mayb u might wanna think about spraying ur backyard so he doesn't get bitten again.....but so glad to hear Zack is feelin better yay!!!
