We have 4 cats but I've never known this with the others. This kitten has been sick maybe 9/10 times in the past 11 months of her life, so roughly every 3-4 weeks since we've had her.
She is the only one of our cats who brings animals in (2 birds, 1 mouse) so far.
She eats James Wellbeloved dry food and whiskers kitten food, with the occasional treat of Cat Milk and Dreamies.
She is only ever sick once in the home but then she scurries off so I don't know if she vomits further. She's quite slight rather than plump, but her mum was very dainty too. She's very much an outdoor cat, spending most of the night outdoors whilst the weather is fine.
Any ideas what might be causing her to be sick? Her sibling from the same litter has never been sick to my knowledge, not once in our home!
