Using vaseline petroleum jelly

Q: Are these halaal? 

Mineral oil, Paraffin, microcrystalline wax, tocopheryl acetate, fragrance. 

They are the ingredients of vaseline petroleum jelly skin protection. I searched them and mustakshif app said its haraam. I have a little amount of this on my shirt and phone because it was on my hands. 

Giving a stray cat to someone to look after

Q: If I find any stray cat, I don't know if the cat belongs to anyone. There is no belt or collar or anything. I tried to look if anybody is searching for his cat. 

If it seems that nobody is claiming it or somebody has intentionally left it, can I take it and give it to someone who will take care of it? The cat will not be able to get food and survive well on its own on streets.
