Erin Caldwell
Pet Technology Editor
Leads AIBUYLAB pet coverage — smart litter boxes, feeders, water fountains, GPS trackers and cameras for cats and dogs.
Erin Caldwell is the Pet Technology Editor at AIBUYLAB, where she covers the connected gear that has moved into pet households: self-cleaning litter boxes, automatic feeders, water fountains, GPS trackers and pet cameras.
She works from published manufacturer specifications, verified retailer listings and publicly documented expert coverage, and states plainly when a claim cannot be sourced. She is not a veterinarian — pet-health content on the site is paraphrased from veterinary sources and clearly labeled as general information.
You will find her byline on every pet product review, comparison, best list and buying guide on the site.
How Erin Caldwell reviews
- Read the draft against the sourcesEvery claim in a draft must trace to a listed source — the manufacturer's product record, an official retailer listing, public user reviews, or a named professional reference. Anything unsourced is cut or sent back.
- Check the numbers a reader would checkSpecifications, prices, review counts and availability are re-checked against the live page where possible. A price is only printed with the date it was verified on; a link that cannot be verified does not ship.
- Edit for honestyClaims that overstate the evidence go: hands-on testing we did not do, expert endorsements we do not have, or a 'best' pick with no published score behind it. Coverage states plainly what is sourced and what is not.
- Sign it and date itPublished articles carry this byline and an updated date. While our editorial roster has one editor there is no second-editor reviewer line — the line returns automatically when a second editor joins.
