Rosie, my cat is exactly the same, thankfully we've found about three kinds that she likes so can usually get something she'll eat. I'd stick with it too, does she have biscuits down too and she's eating those? She won't starve then!
Just back from my 34 week appointment, I had a cover midwife too, she was very businesslike which is the opposite of my normal midwife! Urine sample, blood pressure and heartbeat all good, size all fine, hooray. I mentioned the couple of days of dizziness I'd had and she took some blood to check my iron, hopefully that will come back fine, I've heard the iron tablets are horrible! Only two weeks until my next appointment, things are stepping up a bit now! She asked me if I had my bags packed and told me to get on with it...
Being ever so organised I bought yet more of the boring bits for after the birth on my way home, wet toilet wipes and lactulose. First-timers, I cannot stress this enough - buy some laxatives in advance (breastfeeding-friendly if you plan to, so lactulose or fibogel). You might not need them but if you do you'll be glad to have them to hand. I felt so ill with constipation in the week after the birth that I couldn't go out to get them myself, had to rely on DH and he came back with something super weak. Said they didn't have any lactulose but it's over the counter only (because it's way better than the alternative) and I bet he didn't bother to go to the proper chemist.
Sorry, that was quite a tangent...
