Apple seeds contain amygdalin, a compound that releases cyanide when crushed or chewed. A cat would need to eat a large number of crushed seeds to reach a toxic dose, and swallowing a few whole, unchewed seeds is unlikely to cause poisoning — but seeds, stem, and leaves should still be removed, since crushed seeds and the choking/blockage risk from the core are avoidable hazards.
Peel the skin and remove the core, seeds, and stem before serving. Cut into very small pieces given a cat's smaller mouth and throat, and offer only as an occasional treat.
Apple seeds contain amygdalin, which can release cyanide when chewed. A cat would need to eat a lot of crushed seeds to reach a toxic level, but seeds can still cause stomach upset and should always be removed before offering apple to a cat.
Yes, once washed, in a tiny amount. Remove the core, seeds, and stem, and serve only a thin slice.
Plain unsweetened applesauce in a lick-sized amount is not toxic, but many products contain added sugar or spices, so it is simpler to skip it.
