They get a chip when they get their vaccinations @ 8 or 9 weeks
I got my dogs chipped at three mo. And started there vaccines as soon as vet. Recomended
If your kitten is old enough. The vet/technician should let you know if there's anything with your pet that would make it unadvisable. Another common option is to have your pet chipped when they are "fixed", by which time they are definitely old enough.
I think if they are old enough to be Vaccinated they are old enough to be chipped.
I would call the store and ask them to get a solid answer.
