Adopting a Russian Blue 3 -ish year old male Cat

I live in Israel, in the Negev, and sadly a Russian Blues' owner had to go into a convalescent home. Rather than see the Cat be put down, or pine away from loneliness, I am adopting "Jeffery" (named after a Police Officer who was head shot and killed in 1991, whilst I was a Paramedic for that same Police Department. I myself am a widower, and although "Jeffery", of whom I have only met twice, is a little 'wary' of me, I am of absolute conviction we will get down famously.

I live by myself, and outside of the price of Jefferey from the SPCA, I am spending one thousand dollars on food/toys/litter box(es), litter, food, scratch pads, a cat bed, and so on.

My question is that my apartment is rather small, and I wonder if it would be within appropriate means to put a cat harness on Jeff and take him for walks to the local park--of course, Jeff will have all POSSIBLE vaccinations so as to prevent any disease, and Jeff is neutered, so no little Jeffries to surprise any one. If this is OK, do I need to fabricate 'booties' for his Paws to prevent chafing/injuries? Any info would be most appreciated!!
