Lovely story about Topol, Pav.
George'll be checked for a chip when he goes for his neuter, Pav, but as he's entire boy, and a fighter to boot, the vet we use for stray neutering (not our usual vet - another story that) is always happy to neuter strays, erhem "before we find his chip"
Obviously if he's chipped we'll make every effort to re-instate him with his real owners again, and without his meat and two veg he'll maybe stay there this time
The collars I use to identify potential strays have my address and phone number on, so anyone seeing the collar can talk to me about the cat, and we can get plans in motion for its rehab if necessary.
I also use these collars on my Theo when he gets his wanderlust, I've had people coming round trying to warn me off "their cat" who has been sleeping on their bed for a few weeks, and "always looks so hungry" (Theo could eat for Englnad)
Only when I show them his huge insurance premiums and microchip certificate do they get the message and stop feeding him
And yes, I notice I get strays coming here because my garden is full of abused and discarded catnip and valerian toys which seem very popular too!
