It's a tricky one, if things are tight then I think you should be strong and just get the one. I would love another cat (or two
) but I want my two to have the very best when it comes to food, litter, insurance etc and my budget just can't stretch to another.
Having said that as a student you may be eligible for help with neutering costs from Cats Protection - all the other costs will double though, food, jabs, microchipping, cattery fees etc so if a job isn't guaranteed at the end of your studies then it's probably sensible to stick with one
I put the money aside for my cats boosters (£2.50 a month per cat) so instead of having to fork out £60 when they need doing I have the money ready for it.
When my two were babies I came home at lunch time to check on them and feed them as little kittens need 3 or 4 meals a day when they're still tiny babies.
