Can animals cross their eyes?

Can animals cross their eyes?
If they can, this poses 2 more questions:
Firstly, what benefit can it be to any animal to be able to do this?
And secondly, if they can't, that leaves us humans as the only ones that can. So one would assume that this ability must confer some evolutionary advantage on us, and if that''s the case, what is it?
Interesting, eh!!

My old Siamese cat is cross-eyed...

First, I reckon only hunting animals could (not to say can) because your eyes need to be set in the front of your head to be able to cross them, so rabbits, cows, horsesetc are out. There was definitely a cross-eyed lion in the old TV programme Daktari, so it definitely isn't just us.

It's a natural result of being able to focus on objects at close distance and also being able to look to each side.

OK, that's interesting. Hadn't really thought that through, but of course, you're absolutely right about the ability to focus on objects at different distances, and of course about the difference between the visual set-ups of animals with eyes on the front or side of their head(s?).
Also, I'd forgotten about the cross-eyed lion in Daktari. Must have made life a bit weird visually for the poor creature!
All this reminds me - I really must make another appointment at the opticians.
