Cats won't teleport correctly

When I was going across water ( a ocean) I realized that my cats weren't there and I went back and my cats were the last place I left them. I used a boat to get 1000 blocks to my house but when I went a smaller distance they teleported. So I found that cats won't teleport over a long distance of water, I am not sure if this is only cats. This teleporting issue may also be for other teleporting mobs although I am not sure about that. Please fix. I am also sorry I can't attach any photos or videos.
