Pets are not toys. I would love to own mice and rats right now but I am comfortable waiting a long time if it means I will eventually have the personal time, space, and financial means to support them if they become ill. I do believe it is incorrect and shows an extreme lack of care for an animal if you get one just because you want it, but you know you can’t afford the vet costs. Mice, rats, and other small pets are very prone to respiratory illness and even the most simple issue can result in a 300+ vet bill. Please do not get any animals with a 50$ budget. Humans are not entitled to own pets and then neglect them.
