Cat scratchd toddler few times toddler somtimes provokd i put cat out to wait solution hes gonewas i wrong?

i had tried to seperate them ,making a play area in basement for cat, cat has a mini dog playmate as well as well as working with my little one by showing animal bites that were accidental in videos and so on, i finally had chosen to possibly declaw or find a new home and was in the process of making arrangements for either of those though it was heartbreaking as the cat is amazing and was rescued by me and her from the banks of a river 8 months ago and such a part of the family though still a bit wild as animals can tend to be and i put him out after the last scratch he never returned i am sad and i wonder what else i should have done..he started 2 spray as well lately due surely to a neighbors cat that had broken in to my basement via the dryers vent and sprayed the basement in multitude and i was going 2 get him spayed at the vet this week as well...4 this new problem is it possible the other cats odd behavior and roaming around outside spiked a little more than wild in my cats behavior in the recent history i described..as it seems i was closer to domesticating him up until 2 months ago via scratches, when these neighbors moved in? as well they just moved out this week and took their cat..if he comes back should i try again hoping??
