Teat P is a latex teat for cats and rabbits — the two animals the product title and Wombaroo's own description agree on.
They disagree on the rest: the title lists possums, the supplier description lists guinea pigs. We have not resolved which is right, so no wider species list is given here. PeekAPaw can check it with Wombaroo before you order.
The sleeve seats on any 18–24 mm bottle neck, the Wombaroo Feeding Bottle included.
Hole size and how to feed
The teat has no hole when it arrives. Pierce the tip with a hot needle to about 1 mm in diameter and check the flow: milk should drip slowly from an inverted bottle. A very small animal can be fed from a syringe with the teat pulled over the end, so the plunger sets the rate rather than the animal. Guidance should be obtained from experienced carers on correct feeding technique. Wash, dry, and store away from light.
