My cat had four kittens 3 days ago and they all appear to be doing fine but I am concerned about the mother. Her breathing seems to be quite fast and occassionally she is opening her mouth almost like trying to cool herself down. The house is currently 24 degrees celcius and her ears feel quite warm. Is she overheating? Apart from this breathing fast she is eating and drinking ok is alert and is looking after her babies really well. She is using the cat litter tray and there is normal faeces and urine and only the occasion blood spotting from where she gave birth. Perhaps I'm just being over cautious but I'm worried it might be milk fever. Its her first litter and I'd rather be safe than sorry with my cat and her kittens. Any advice would be gratefully received, thank you.
