Buy OSRS Seasoned sardine
The Seasoned sardine is a quest item in Old School RuneScape. It is used in the Gertrude's Cat quest. Players give it to Fluffs, the lost cat, to calm her down during the quest.
To make one, use doogle leaves on a raw sardine. Making it takes 2 ticks, which is 1.2 seconds. You need partial completion of Gertrude's Cat to create it.
This item is not like a normal raw sardine. You cannot cook it on a range or fire. You also cannot turn it back into a raw sardine once it is made.
The Seasoned sardine weighs 0.12 kg. It is tradeable and noteable, so you can carry it as a bank note or trade it with other players. It is not equipable and it does not stack in your inventory. Its in-game item ID is 1552.
This item is a simple but needed step in Gertrude's Cat. If you want to finish the quest without gathering doogle leaves and a raw sardine yourself, picking one up saves time.
