Does anybody here give Pet Natural's L-Lysine treats to kittens? Are they safe?

my kitten has been sneezing with no other signs of URI, i plan to give him l-lysine (250mg) daily for 3 months. I saw Pet Natural's treats containing 250mg L-Lysine, but most treats are for adult cats so i was wondering if it would be safe to give them to my 11 week old.

He got constipated today after eating temptations and greenies treats though. (I will not give him temptations until he's a year old but i will continue to give maybe 2 greenies treats a day for good behaviour)

I use the Now brand of L-Lysine. It is a powder form and mixes so easily into canned food with no bitter taste. Even my picky girl will eat it right up. I would think the threats would be safe to give a kitten, though. I tried offering the Pet Naturals Lysine treats to my girl and she wouldn't eat them! :lol3: I can't see anything on the bag that says not to give to kittens. It is a natural treat with the addition of the Lysine. Should be just fine and safe to give.
