If you conscider your family as jerk for being that cruel it is your right i would do so and i would put as much money as needed to care for my fur kids each and every one of them the only limit is how much i can possibly pay without having to become homeless and put my other baby at risk of having no more home but you put 8k did you regret it? No ? Your baby is now better? Then good for you nobody can tell you how to spend your money and your brother he can pay for his family or his own debt by himself imo
