I have two lovely bengal cats. One is extremely small - she is about the size of a 1 year old even though she's six. We got her from the RSPCA and she had health problems - she basically has a permanent snotty nose and she sneezes and coughs a lot. She has a mucus thinning powder for her food and a lysine fish oil supplement.
She's currently feeling a bit more coldy than usual (has been to the vets and had antibiotics and an anti-inflammatory). She's now acting much more like herself, but has no weight to spare and isn't eating. She's sniffing at food but not actually eating it. I'm heating it so it smells more and hoping that she'll fancy it a bit more later.
The problem is that she is generally not interested in food. I really want her to gain some weight so that when she is more run down than usual she has a bit of fat reserve. Is there anything I can do to help her gain weight? (Complicating things our other cat, who is healthy, eats like a maniac and would eventually eat all the food for our small one). Would be grateful for any advice!
