This has been an interesting discussion! I am not on benefits as such, but I am a student, I do rely on student loans and my student overdraft and I have just taken on a new cat, I also have a tortoise, a lizard and a bunny to care for. I have in the past and will in the future, go without things myself if my pets needed medicine or toys and so on...but I also live with my fiance who does work full-time, although he is not a high-earner. We are saving up to get married, but, should any of the pets need money spent on them, the wedding fund would go!
I think it does depend entirely on the person, my mum's financial situation has taken a downturn, and she has pets, but, like me, she would go without first. I think whether someone takes on a new pet whilst also on benefits depends entirely upon the person and their attitude towards their 'masters'. A lot of people who struggle financially with pets will find a way to care for them or pay for medical treatment, some though, will not bother trying to find a way to pay for their pets, will not do without themselves and will expect handouts.
I have also suffered from mental health issues in the past and have found that my pets have been such a boost for me and I couldn't imagine doing without them now.
I do not go out, occasionally have a glass of wine at home, I don't smoke, I chose to spend my money on my home and family (my family includes my fiance and all the pets we are owned by!)
A friend recently suggested to me that I could go to PDSA should Benji need any medical attention due to his FIV status, but the way I look at it, I have savings I can raid to pay for any bills and I chose to take him on, he is my responsibility and I would rather pay for his needs myself
I think anyone who believes they are 'entitled' to anything from a charity should have a deep re-think. If I was struggling I would be grateful for any help I could get, but would not believe I was entitled to it, if that makes sense?
