This is my nanas cat Misty, she likes to roam and has been gaining weight and her appetite has increased, when stroked she tends to purr a lot but mostly likes to be by herself. As this is my nan's first female cat she isn't sure as to whether she is pregnant, her nipples have gone a little bit bigger but still we are not 100% I thought we'd check this site for any ideas before arranging transport and time off work to get her to a vet. Any help would be greatly appreciated!
