There are three ferrel cats that come to eat and sleep in my back patio. I had neutered so they adopted me but will not let me near them. They are all about 18 months old now. I got them fixed about a year ago and they responded well to Abound No grain cereal and canned food
. Inside a month they were all pretty fat because they also ate somewhere else, I guess.
Other ferrel cat's and neighborhood cats would come when I wasn't looking and eat some of the food. One dominant male seemed to scare everyone else away. He always looked sick so I ran him off when I could.
Now since about a month the three cats I had fixed are skinny and look weak loosing a lot of hair-big, big chunks. They don't eat much and often leave the food for a day. I give them fresh water almost everyday and clean the bowls each time.
Is there any vitamins or minerals I can give them in their food or energy boost to help them out.
I thought of capturing them and taking them to the vet but I can't afford that expense plus I don't want to take any risk of contamination in my house or car. I have a small sedan. I also have an indoor cat and a large breed dog that have never been in that patio. Its really a home for the ferrels and a toilet (very large gravel area).
If you could suggest something just so I don't have to watch them wither away before my eyes, it would be great.
BTW I live in Glendale Arizona in a townhome community in an almost rural area of town.
