I have 4 cats and they are all different in what they eat. Roony will only eat biscuits will not touch wet food at all. Not even if you give him freshly cooked fish or chicken he just looks at you and walks off and will only eat chicken flavoured biscuits. Snowy his brother mainly eats biscuits but will every now and then will lick the gravy off of wet food. Patsy my old cat has a mixture of both she has biscuits down all the time and will have a pouch of meat at night at min but in winter normally in a morning as well.Sophie who is 16 weeks prefers her wet food she has whiskas kitten and applaws kitten and nibbles on biscuits every now and then. I feed mine rc biscuits have bought applaws meat for both cats sophie loves it but patsy seems to prefer asdas own make or whiskas. I admit mine are very spoilt and pampered roony has bath tap on all time as he prefers to drink water from there. If we are away though he drinks out of bowl hubby says its because i spoil them
. I tend to just go with what my cat wants and all my cats have had a mainly dry diet and have all lived to good ages chloe was 18 yrs old when i had her put to sleep and she only ate go cat or asdas own cat biscuits as that was what she liked and she never had any health issues until the last couple of months of her life.
