I know this isn’t to do with women’s health but regards to my elderly/senior kitty

Hi , so my cat who’s 14 is limping won’t let us touch her paw. At all or look at it I’ve saw a glimpse of her paw normally her paw pads are a light pink ( cute. I know ) but I’ve notice part of her paw pad is like a redish brown. ? … could it be her claw digging into her paw or .. infection..? She won’t let us touch it and we can’t afford a vet. Nor we don’t have a pet carrier for her …

Edit : here’s a pic that looks like her paw pad

I’ve notice it’s on both of her front paws right is more severe
