Pet-Ag Nursing Kit - 4 oz, Pack of 2 - Promotes the Natural Feeding of Liquids to Baby Animals - Each Kit Includes 4 oz. Bottle with Cap, 3 Nipples & Cleaning Brush

We recently rescued two orphaned newborn kittens who, obviously, had to be bottle fed. I bought a variety of bottles for that purpose in the hope that that would make it so I didn’t have to wash bottles as often (that was naive of me, lol). Out of the three bottles I tried (Petco brand, Petsmart brand, and these PetAg) the PetAg ones were BY FAR the best.The plastic on these bottles is flexible enough that when your kitten gets a good latch, it creates a nice vacuum seal allowing the kitten to drain the whole thing dry. The bottle will crumple when this happens, but we haven’t had a single bottle tear or break even when it was crumpled almost flat. The screw-on lids fit nicely with no leaks. The nipples that come with the bottle were great - one kitten we had would throw a fit if we tried giving her any nipple other than the PetAg one. I don’t understand it, but whatever, she ate. (We also used Miracle Nipples which the other kitten adored, I recommend those too!) Despite countless washings, scrubbings, boiling to sterilize, and microwaving, the PetAg bottles still have most of their blue ink labels long after the other bottles’ labels wore off. And the measurement markings are not printed, they’re part of the actual plastic, so those will never rub off or disappear. Our kit also came with a cleaning brush that perfectly fit the bottles and got the insides sparkling clean.That being said. I was so impressed with the PetAg 2oz bottles that I went out and got some of their 4oz bottles to use when the kittens got bigger. I had to search HARD to find those 4oz bottles - and I’m pretty sure I know why. They suck. I bet PetAg stopped making them because they suck SO bad. The plastic is different, the screw-on lids leak all over the place, the nipples are weirdly hard. Altogether a bad time. I was SO disappointed, expecting the same kind of quality as the 2oz bottle, just bigger. Nope. They might be the same brand, but the 4oz bottles are entirely different. DO NOT get the 4oz bottles. Just get extra of the 2oz and prep two bottles for feeding time!

These bottles are huge. They are not for kittens as the description states.
