Has she or could she have had any contact with an entire male whilst since arriving with you?

The picture is difficult, he nipples do look slightly pinked and full - my best advice would be to take her to the vet for an ultra sound

What circumstances did you get her? She is a little older than normal to rehome.

It is advisable to neuter girls by 6 months as well.

I went to the breeder to purchase a kitten and my daughter saw Nala. The breeder said she was for sale also at a cheaper price because she was about 6 months old. The breeder doesn't spay/neuter her kittens before they go to new homes. I don't have a male cat and she is indoors so she hasn't had access to a male here. She also hasn't gone into heat since I've gotten her. She has an appointment with the vet tomorrow.

the vet will clear this up and give you answers.
Swollen or hardened abdomen can be a symptom of illness so its good to hear a vet will be checking your girl out ''hands on'' tomorrow

Can you book her in to be neutered like tommorow? Even when older cats and bengals can have a hard time, let alone a kitten baby at 7 months old giving birth She may just be coming into call, some of mine go a little pink when they do, did the breeder have boys about?

The breeder lets all her cats roam free in the house so she could have been exposed to a male. The vet doesn't believe she is pregnant, thinks she is just eating very well My vet does not have an ultrasound machine but couldn't feel anything. He thinks we are in the clear and made an appt for her spay.
