Fish as a birthday treat?

Hey

My two kittens are growinh up, and will become 1 year this weekend.
I want to give them something extra nice to eat for dinner, and tuna is good. Well, there are dissagreements.
Apparently the canned tuna have a lot of salt added, which is bad.
So I was thinking salmon. Also thinking of having it in the oven (plain) so that its not raw. Can this be bad?
Mostly the stuff I have read is people talking about long term use of fish as foid, which can cause problems with vitamins and such

But I sm just going to treat them to something I think they will rally like for one meal, and well not a whole salmon, just a little bitt, more like a little dessert than anything.

Anyone that can help? Cooked plain salmon woth no bones or skin? maybe a little oil... What oil then to use? Olive, soy... Have not investigated oil and catdiet before.

I think giving them a birthday treat is a great idea, I would also consider canned sardines in spring water or olive oil, my guy LOVES  it 

Plain uncooked fish would be best. If you prefer cooked, just gently poach or steam the fish in plain water.

Yep, salt-free sardines or cooked fish with no seasonings would be good. My cats LOVE Fancy Feast Fish and Shrimp Feast, so that's what they get for a treat . It's just shredded fish with a tiny shrimp on top. . .they love it.

My kitties also love Appetizers (now Purely, I can't stop calling them by the old name though!). Sara loves the one with the shrimp - she'll eat everything but the shrimp, then at the very end will devour it.

If it's a once off treat, you can give them what they like.As you say, the problems with fish are associated with long term feeding based on it.
