It is great that you would like to foster but please make sure that you have thought about it carefully.
It isn't just about the money, but also the time and dedication. You wouldn't be able to just hand them back if you decided you couldn't manage as you would be relied upon and be expected to look after them if they become poorly.
I know a few people who foster and although veterinary fees are paid, I think you would also need to spend some of your own money too.
I know it isn't the same thing but we take care of a pair of degu's in school holidays (13 weeks a year) as my husband is a teacher and although the school would cover vets costs, I pay for the food and bedding from my own pocket and treat them to toys as well because I am doing it to be kind and helpful.
Previous to this, we looked after a pair of rats. We ended up taking them on full time but that's another story. One of them suffered from URI's (which is one of the reasons we eventually took them full time) and although the school paid the vets bills previous to this, I paid the bills until the school could reimburse me.
I see that your landlord has no problem with pets but if you did go down the fostering route, could you get this written in to your contract agreement? This is what I did when I lived in rented accommodation.
I'm not trying to put you off but it is a big commitment.
If you do decide that it isn't for you, could you not sponsor a piggy instead? There are hundreds of piggies who will spend the rest of their lives in rescue due to health / behavioural problems but they still need someone to care for and love them too
