Dear patient Has your cat been immunised? Previously had you taken injection t.t and when? If it was taken in July no need to taken inj. T. T again. You need to ideally take a booster and observe the cat for any sort of rabid symptoms ex- salivation, aggressive behaviour, intolerance to light and water etc. for the next week or so. if these symptoms are present take the 2nd and 3 rd dose as well. Or else only one booster should suffice ( because it’s your pet cat)
