Is Smokey fixed?
My cat Jake(who is an inside cat) gets out too, he see's my son open the door, he is going with him. Jake is fixed & has his claws as well. When he first started getting out, he would hide in the woods next to the house.. OMG! what a pain in the arse.
I used my broom to scare him out of where he was hiding, & he would run to the door he came out of. Try, & give some cat treats (my two are pigs when it comes to treats).
NOW.. he just sits at the door & waits! He gets out probably 1-2 times a week. And he comes back!! He knows where he can get some love, food & relax!!
I hope you can get Smokey inside soon!!!
