Managed hidden - Not a cat

Here I leave you the information to get the hidden achievement "It's not a cat" and be able to complete the achievements 100%.
If it helps you, I would appreciate it if you reacted to the guide, so you encourage me to continue sharing.

How to get the hidden achievement

The hidden achievement is called "It's not a cat" and, as its name suggests, you have to locate other animals that are not cats, but seagulls. There are 4 of them in the image and they are all on the right side. When you click on them, they will turn red. Once you've located them all, you'll earn the "Not a Cat" achievement.
I attached an image for help.

Há 4 pássaros escondidos no lado direito (um é bem pequeno) e um 5º pássaro no topo do telhado do lado esquerdo. Acabei de refazer o nível da conquista que faltava e ela apareceu assim que cliquei

There are 4 birds hiding on the right side (one is really small) and a 5th bird on top of the roof on the left side. I just redid the level for the missing achievement and it popped as soon as I klicked on the fifth bird. :)

Found 4 of them the achievement didn't pop and then I found a last one.
So there's 5 seagulls hide on the right side

I did that and didn't get the achievement :(
