Our neighbours got a kitten around the same time we did. Ours was 8 weeks old when she arrived and theirs (male) appeared to be about 5 or 6 weeks old, already having been through another home, and very small. They feed him a very poor quality adult cat food (we share a recycling bin). He is now 4.5 months old and about the size of an 8 week old. They have allowed him to roam outside unsupervised since the day they brought him home. We're in the city on a high traffic intersection with an alley full of tomcats, raccoons and coyotes. He's never seen a vet. No vaccinations, no checkups, no deworming and they told me they don't intend to neuter because of the expense. It is obnoxious to offer unsolicited advice or to pass judgement on someone who chooses to raise their child/pet differently than you. But at what point does questionable pet parenting become neglectful or abusive? I don't see him living long without intervention. How or when does one intervene?
