Right folks we're getting into mid October time now so...
If you live in an urban (built up) area then it's time that mogs start stopping in for the night.
The risks to cats out in the big wide world are at their absolute maximum for the next 4 weeks or so - from car accidents as we settle into the longer nights and earlier sunset, the risks that come from a cat being frightened by a firework and getting him/herself lost, shut in somewhere or bolting into the path of a car, the (unspeakable) risks borne by unpleasant children who seem to give themselves free license to do as they like at this time of the year, bonfires, candles, fireworks - it's not a nice world out there at the moment if you're a cat.
This is of course only my opinion but even if Puss is usually accustomed to going out after tea and strolling in in time for breakfast, you seriously ought to think about shutting them in for now. Yeah, they'll whinge. They'll get over it. If you let them out and something awful happens, you won't.
Let's all have a lovely safe peaceful Autumn.
