Have Cat Questions? Ask a Cat Vet Online.
No. Unfortunately, you will have to see the vet or get vaccines for the mom and kittens. This is pretty important with strays so you want to be sure and get this taken care of.
Some cat rescues offer programs for strays and will spay and neuter them for free and give vaccines. You should give your local humane society a call for a referral.
Let me know if you still have questions.
