You need to make sure that it doesn't have any onion powder in it. You also need to be sure it's not his primary source of nutrition. Baby food lacks all of the essential nutrients he needs. There are several deficincy's that can be life threatning.
The only time my cats get jarred baby food is as a treat at shows. My kitens get the dry baby ceral mixed with Just Born or KMR and make it mush so they learn to eat solid foods.

I give Arizona a little as a occasional special treat after particularly heinous chores (medicating, bath, etc.) I also buy the Gerber--we've tried the beef in beef gravy and the lamb. She loves them both--I am instantly forgiven the minute I pull out the jar.
