Cats should not eat fruits with large pits, such as lychees. Fruits with large pits include peaches, pears, mangoes, and lychees, because the pits are not suitable for cats. Furthermore, the pits contain the toxic substance cyanide, which can easily cause poisoning if a cat swallows them while chewing.
If you want to feed your cat this, try to remove the pit before feeding it. Do not feed it too much, as excessive intake can cause vomiting, diarrhea, abdominal pain and other symptoms in cats.
