This may be a bit of a long shot but our cat went missing 6 nights ago and we are desperate for his return

He isn't much of a wanderer and didn't often leave our grounds. We live very close to the Green Valley complex. He is a silver black tabby with green eyes and he is 2 years old. He was wearing a green collar with bell and is very friendly. He responds to the name 'Bubs' and he has also been neutered.
I know that there are so many street cats in the area so it is hard to tell one cat from the other but if anyone has any info i would be really grateful if you could contact me through my profile. Thank you.
