@Aura lol, so your cats are against you, their master?
Well, my sister had two small birds (forgot what birds they were in case you want to know). And well, they fell ill in a week or so, my sister was really worried for them, she tried giving them some medicines, I don't remember anymore from where she bought those medicines or from whose recommendation she bought those medicines. But after she feed them those medicines, they later died. And the poor girl cried for them while my Mother laughed at her for that (that's right, she laughed for crying for them).
